Edit: Some of this info may have been posted. Just Confirmation and a little new info I was just searching online and came to the website, Sherdog.net and it has some info about TF4. Not so much new information, but a confirmation of what we have been hearing. Mark Walhberg will be the lead, but the two "kid leads" yea seems like the whole Race car driver thing is turning out to be semi-true. And the fact that all actors are having to sign a 3 movie contract indicates a second trilogy in the works. "Director Michael Bay is set to begin testing actors to play the young male and female leads in Transformers 4 under star Mark Wahlberg. Sources tell The Hollywood Reporter that Transformers 4 has a story that centers on Wahlberg's character and his daughter. In addition, the daughter’s boyfriend, a race car driver, is the third lead in the film. Testing for the daughter and boyfriend roles is set for this week. Among those vying for the female role as Isabelle Cornish, sister of Australian actress Abbie Cornish (Limitless), and Nicola Peltz, who appeared in M. Night Shyamalan’s Paramount movie The Last Airbender and has a part in A&E’s Bates Motel. There are five young men testing: Luke Grimes, who appeared on ABC's Brothers & Sisters and is in Taken 2; Landon Liboiron, who co-starred on Fox's Terra Nova and will be seen in the upcoming Netflix series Hemlock Grove; Australian Brenton Thwaites, who starred in the telefilm Blue Lagoon: The Awakening; relative newcomer Jack Reynor; and Weeds co-star Hunter Parrish. Sources say Paramount is signing actors to strict three-picture deals, but no one is balking because the chance to be the next Shia LaBeouf is seen as a huge opportunity."
