Yeah but I think when origin stories have already been TOLD that's why it is annoying. Iron Man and Cap were required to have origin stories, honestly. As well known as they are to us, the general population had NO IDEA. I'm fine with Hulk being glossed over, and Spidey now, because their origins had already been told at least once.
His Peter always sounded like he was suffering from crippling depression... and that was while IN the suit. Out of the suit, he sounds like that emo kid at parties who brings up soldier suicide rates in Iraq.
Face/Off is more of a meta-example for him and Travolta of how good they really are as actors. Yes, the movie is ridiculous, but consider this: at various points in the movie, you have John Travolta playing Nic Cage and Nic Cage playing John Travolta, and seeing what they can get away with in terms of characterisation. To make it even funnier, they take it even deeper when they're around other characters not in on the joke, at which point you have John Travolta playing Nic Cage playing John Travolta, and Nic Cage playing John Travolta playing Nic Cage.
Head exploded yet? It's because Travolta and Cage Inceptioned each other.
Travolta talking about creating both characters with Nic was interesting. How they spent hours just talking to each other figuring out each other's mannerisms and crafting both the characters. The movie if nothing else is great for actors studying the art of becoming a character because you have both actors switching places halfway through the movie.
