Although it seems I already told you many things (and many other people too), I decided to say a bit more, because of plenty of interesting details. Firstly, a bit of my emotions! I want to say an incredibly huge THANKS to everyone from the crew and especially to action camera specialist Yuri, who REALLY helped me to fulfill my dream! Then a big thanks to TFW members Tikgnat and Sol Fury, who so much worried about me and tried to help me in difficult situation. And of course, I must to say thanks to everyone member from here who gave an information about filming! Thank you guys! It was unforgettable experience!Unbelievable how fast and coherently crew was working! They even ate on the set  Because of lack of time  And seeing Bumblebee, racing at 60mph like a beam of the sun was awesome!
Monday 5th September Holborn, Lincoln's Inn Fields, Sir John Soane's Museum
Interesting that sir John Soane, great British architect and collector of antiques, was an author of building of Bank of England, near which there was filming in weekend. Soane's building was almost demolished in 1920' only first 3 floors remained.
So I watched scene in which cars with TRF soldiers, policemen and agents (maybe MI6) fast approached the museum, later they filmed a scene with soldiers inside the museum.
I also have seen Laura Haddock inside and later learned that Mark Wahlberg also was there. One man from crew had a badge from TRF soldier's beret and said a full name of TRF  Transformers Res...tion Forces. But remind it maybe fake! They filmed inside building till 8-30 pm after sunset.

Thursday 8th September filming in Brentford, Syon park, Great conservatory First appearance of sir Anthony Hopkins character

Friday 9th September filming in Goldsmiths' Hall, (Venue Hire - The Goldsmiths' Company), Foster Ln, St Paul cathedral region, City of London. I didn't catch anyone except Jonathan Sela, but have seen plenty of powerful lights along second and third floor of the building. Since that evening they started preparation for major filming in the City. They blocked roads on Gresham st, Lothbury, Moorgate and all small streets towards Cheapside. Main events later was at the cross between Princess st, Moorgate and Lothbury, near Bank of China and Bank of England (it's huge) Very beautiful borough, classic 19th century buildings contrasting modern City's skyscrappers on horizon

Saturday 10th September I was there at 8:30am. Have seen Hound (It's difficult not recognize him , Crosshairs, Drift, Hot Rod and silver Aston Martin. Bumblebee was still in closed trailer. Noticed some activity near, Armoury house, beautiful building with statues of knights. There was a row of TRF's bulletproof vests in front of building. Quite soon i've found a filming - it was a race of now-famous red McLaren and several TRF Lexus and police cars. Crew members prohibited me to take photos so I could use only phone. You already have seen them

 

Sorry guys i need for sleep now  Stay tuned! photos coming

 

Thanks so much for your info! I actually mentioned you over in a YouTube comment section (regarding the identity of the McLaren, ) for a RaginNation video on Transformers 5 London filming.

I also figured that MI6 was involved in the plot, and I suspect that Anthony Hopkins and Laura Haddock are employees of MI6.

 

So photos from the first day Laura Haddock and crew members. That dude who's drinking water is often near Michael Bay. It seems he later called McLaren "Lady"
Ian Bryce, producer, in official cap. Many of the crew wear similar caps including Michael Bay. Someone has cap with Megatron

Laura Haddock inside museum
Rolling! TRF soldiers approaching museum

TRF officer. That guy, who's talking with him, said a full name of TRF

 

In last photo, the guy's hat has a Cemetery Wind skull on top of TRF logo.

 

I guess Cemetery Wind didn't really ceased operation even after the death of Harold Attinger. Now I really want to know what TRF actually stands for.

 

Second day. When I've firstly seen the race with McLaren, I've thought that he's Autobot and TRF pursuit him, because he rode wiggling from side to side. In the next scene one of police cars, riding behind him, collided with black cab Hopkins double was in McLaren during that scene. In some time I also have seen Mark Wahlberg double near McLaren, but there wasn't filming that time

 

Then heavy rain started and crew took a break for lunch. Yuri introduced me to action camera team and after talking with them I was introduced to people who make primary editing of shoot material. They showed me that scene with McLaren already in 3D. It was very dynamic race! Then they showed me many photos from Arizona with Mark Wahlberg and Isabela Moner, I noticed Hound and garbage truck there. Then we talked about McLaren and Aston martin and they confirmed that they're Transformers! About McLaren they said that's a "new guy" but they don't know anything about him

 

COOL! Thanks.

I think the garbage truck is Wreck-Gar and I think the Decepticon motorcycle is OilSlick.

 

That's great! You scored a first glimpse at the actual footage of the movie! I'm jealous here, especially, for that look behind the camera.

Has anyone seen the motorcycle anywhere else beside the initial shooting?

 

About 4pm Michael Bay arrived. Where he was until that time I don't know, possibly in another place of filming. Quite soon after that dazzling sun touched that grey rainy day  Bumblebee appeared! They filmed a scene in which he is riding to square, where people are waiting a bus, but suddenly Bumblebee does an abrupt turn and drift, obviously to show his coolness and just fool around    It was brilliant! But the people fled appalled  Michael Bay just have popped from his Land Rover Mark Wahlberg's stunt from the back and assistant of director

capellmeister of orchestra  

Look at him! He's just awesome!



Filming in progress
After that episode some stir began, crew looked confused! Then Michael Bay loud and angry said "Where that car?!" And after a few minutes he arrived. Barricade! Very unexpectable!
Then the crew asked people to move around the corner. I only managed to catch how Bumblebee make a drift under the nose of his enemy and they both rushed to Princess st. I don't see anything else only heard the roar of their engines and screeching of tires

 

All amazing pictures and details. Pretty cool how they even let you meet everyone on set! That's a dream come true honestly, lol, I would love to be you. I guess it's safe to say that TRF is a reborn Cemetery Wind now.

 

Based on what russian fan said, it seems like TRF may stand for "Transformers Resolution Forces". And looking at the skull on the logo, it seems like they're a form of Cemetery Wind. My money is that they're just some emergency response unit that can be called if someone spots a Transformer or some Transformers fighting, and then they show up and either straight up try to kill any of the bots regardless of faction, or maybe try to de-escalate the situation. I just hope they don't target the Autobots again. It's seriously ******ed how they haven't realized by now that the Autobots are not the enemy. Anyone with a brain can tell someone is not the enemy if they're 20 feet tall, alien, and not trying to kill you on sight like a con would.

 

Wow these are amazing pictures! I don't have really high hopes for this film but I can't wait to see all the cars in action (especially Barricade <3)

 

I just joined the site to say wow, you got amazing photos and info, I'm so jealous that I only found out they were filming a couple of days ago! I'm curious, you mentioned that they're coming back to Gresham St on the 21-23rd in your other posts, where did you hear this info? Do you know if they're doing more of the same type of filming? I'm going to London on the 25th and if they're definitely coming back and doing the same thing I'll go a few days early because it looks way too good to not go!  

 

I dreamed about it for 9 years and was waiting for a whole summer sitting on the travel bag! But of course
it worth everything! 
Be passionate friends! don't afraid anything on your way like our beloved heroes! I must say, that seeing crew members' delight when they was learning that I'm from Russia... It's incredible joy for me! Hope, I gave them some inspiration for their hard work!

 

Ha-ha! finally I'm infecting someone  
Firstly, some people from crew said that they will be in UK for a month. And on the Gresham st there was official announcement, that the road will be closed from 7pm 9th of September till 7pm of 11th September, and also from 23th till 10pm 25th of September for filming, unfortunately the date of beginning is unclear on my photo, but it seems it's 23th. The same announcement was at the Gherkin skyscraper. If you have some questions how to find them send a message for me. I wish you good luck!

 

Oh wow, thanks for getting back so quickly! I think I might do a trip from 22-25th September and hopefully there'll be something to see and more people will be looking for them! Will you be in London as well? I hope the road closure means they'll be doing a lot of filming with vehicles outside? Maybe this time they'll get Drift and Crosshairs out on the street because they didn't seem to be used a lot this weekend  

 

Seems like Cemetery Wind went from a US based CIA organization to a world wide organization. Which explains them having different country patches. So they basically became NEST 2.0 but against all TFs.

 

The third day. The weather was sunny and clear, I could concentrate on all events around me. Firstly I've seen that they add Aston martin and Hot Rod on the set, but both under the cover. They filmed scene with McLaren just riding on busy London street among cars and buses without TRF. Then they uncovered Hot Rod and filmed a short scene of him just driving away alone, I heard like Michael Bay called it an ending of act.
After it some hype began to happen, many people gathered at the entrance of restaurant, but some of the crew advised me to stand aside and cover my camera. Just after a couple of minutes Anthony Hopkins have walked near me! 
He sit down in McLaren, on passenger seat and then they filmed a scene how McLaren is riding to the square, suddenly brakes and Hopkins with some anger on his face is trying to out from the car. Don't remember whether TRF lexuses were near, it seems yes. Then they filmed a scene where McLaren is rushing on street among ordinary cars and camera takes a close-up of Hopkins looking out the window. The car stopped and I didn't catch everything, because of trees, but it seems there was another man on square with a walking stick, who approached McLaren after it stopped, he's a lot of gray hair and hairstyle like Bruce Brothes. Then there was very strange thing. I was just standing near Mark Vahradian, producer, he talked with another man and suddenly dropped couple of words about the film plot! I said Yuri about it, he laughed and said that no one can speak about actual plot, but producers speak about it everyday and everyday differently! So if you guys very want, I can say what I've heard, but take it with huge grain of salt!
