Mark Duplass is an interesting fellow. It's not really accurate to describe him as "famous" -- even he admits that he can walk around unbothered pretty much everywhere, and that's exactly the way he likes it. It was only in 'Tammy' -- a movie that he has a lot of opinions on why it didn't work -- did he start to feel the pangs of fame. And he didn't like that feeling one bit and wants no part of your 'Guardians of the Galaxy' or Marvel or 'Star Wars' type movies. Well ... that is unless, of course, someone actually asked him to do one of those types of movies.
