Continuity mistake: Near the end of the movie, when Oppenheimer is being interrogated in the small room, his lawyer is on the phone (we later find out it's Kitty). In a wide shot, he gives Oppenheimer the phone, and he puts it to his left ear. The next shot is a tight shot of Oppenheimer's face with the phone to his right ear.

Leslie Groves: Zero would be nice.
Trivia: Josh Hartnett was one of the final 3 actors in the running to play Batman in Batman Begins, but withdrew. He later said he regretted his decision and wanted to work with Christopher Nolan, finally getting his chance here.
Question: Why are most of Robert Downey Jr.'s scenes shown in black and white?
