I read that article in Empire, sounds like he's scared shitless if you ask me if he's got to compare it to Transformers.
D'oh! Can you blame him. McG is a beginning director. He has to deliver a fantastic Terminator movie to gain fame. Michael Bay HAS made good movies, is well known for his action sequences. McG lacks Michael Bay's experience.
If I were McG, I'd be more worried about Night at the Museum 2 considering that's a film he'll be directly competing against for box office take opening weekend...and also considering the first Night at the Museum outdid T3 by more than $100 million....different years, but still.
