Paulo Costanzo: (On his favorite role) I played a character called Ryan in this movie called Everything's Gone Green ... It was just a nice, depthier role than I usually play. And a role that I just recently played, I played Seth in this horror film called Splinter, which was released by Magnolia pictures and didn't hit a lot of theaters but it did become a cult classic already. It's actually a really, really cool movie ... in fact, I would say that people should see it. It's one of the few things that I've done that I would just urge people to see it because it's just awesome.
Paulo Costanzo: I'm very insecure. I have low self-esteem just like a lot of actors do.
