We’ve already mentioned that Judd Apatow’s stand-up comedian dramedy, “Funny People” will host a bunch of cameos. Norm MacDonald, Andy Dick, Sarah Silverman, Dave Attell already have been mentioned and even Owen Wilson will appear, (albeit only in poster form).
Well, add Patton Oswalt too. (there’s probably a ton more, but these are the only ones we’ve noticed so far). Apparently Oswalt worked on the project for a while and did some “punch up” writing on dialogue and jokes and the stand-up routine of different characters. Evidently even Mayor of Comedy Judd Apatow could use help with a funny line here and there. [Collider]
