"Zodiac" was good. Jake doesn't go for flashy roles too often. He does mostly introverted, intense characters in serious films. He probably won't do romantic comedy if he can avoid it. Those are usually the 'fun' roles done for a lark or the trash bin for actors who couldn't get out of doing them.
I was really excited about seeing "Rendition" until someone spoiled it for me, then I didn't bother. I'll probably rent it some day. I have a few favorite actors. I don't have to like or watch everything they do.
I like romantic comedies, but they are soooooooooooooooo predictable and rote. I can understand Jake wanting something more challenging.
