Thomas Lennon had mentioned that he believes that he plays the same doctor in Memento and The Dark Knight Rises ^^
Obviously not confirmed, but still fun
Basically, I guess -- I kinda of think it's the same character from "Memento." The doctor who's testing Sammy Jankis in that movie. I like to think I'm exactly the same doctor and it's all happening inside Guy Pearce's mind. Whether or not that's true is probably for Nolan to say. I'd like to think that's happening.
