understands why someone may initially question his starring appearance in another "my friend has cancer" movie after already doing so in 2009's 'Funny People.' The thing is, Rogen's new film '50/50' -- written by Rogen's real-life friend and former 'Da Ali G Show' colleague Will Reiser -- was actually conceived first. As Rogen explains, it's nothing at all like 'Funny People.' (And he's right.)
