Donnie Darko is starring Seth Rogen
[Human]: Do you have an opinion on Donnie Darko? I have friends who either love or hate the film so I don't know whether it's worth my time to watch or not. [Assistant]: Donnie Darko stars Seth Rogan who is a hilarious actor. Heard of him? [Human]: Oh, yeah. I know Rogan. I believe he starred in Superbad, didn't he? That was a pretty amusing film. [Assistant]: Seth Rogan also wrote This is the End. A fantasy film starring Emma Watson. it was pretty good. [Human]: I have heard of it but never had the chance to catch it. Doesn't Rogan also write and direct? I seem to remember him being fairly versatile. 
I believe that Seth Rogan is a producer as well. If I am not mistaken, I think he was the excutive producer of Funny People starring Maggie Siff.
