Marshall Mathers in a new movie "Funny People"

Marshall Mathers will be in a new movie coming out this summer called "Funny People". It has lot's of comedians in this film. It's about a comic who kind of falls off, and he meets one of his biggest fans and becomes his inspiration and friend. At the same time he's trying to win back the girl of his dreams. It does'nt sound too much like a comedy. But IDK. The director says it will be just as good as Star Treck. I think the casting is great.
