Mark Duplass on his character Kenneth: This is the first time I’ve played someone like this. He’s borderline insane and a mystery that audiences would like. The big question is for people how they feel about Kenneth is “Is this guy crazy? Or does he actually know what he’s doing?” That was really fun for me to play that [character]…The key was really identifying with his sincerity and his lack of cynicism. I’m a pretty jaded, sarcastic, cynical person to a certain degree.
And I LOVE how pure Kenneth is. He doesn’t make judgments of certain people. Clearly anyone who believes they could time travel is not too cynical. And I rooted myself in just what that would mean. The good news about that it’s a quality that is very, very attractive to people who are lost. When you come across a believer, it makes you want to be with them. It’s what I use to bring Darius (played by Aubrey Plaza) into me. (via)
