John: (On mostly playing supporting roles) Because you get to be free. Not that there's a problem with being the leading man, but the leading roles are always tough. It's hard. It's a really hard thing to do right, to get right, and it's not as fun to be the leading man. Being a supporting actor you have no responsibility. You just go there to play and have a really great time. And you have a really great time. You just go home and you enjoy everybody. When I'm the lead in a movie, you don't sleep, you focus on every aspect of the movie and it's a huge responsibility. And there aren't that many great leading parts, either. There are more, better written supporting parts than there are leading parts.
