Ok I went through the IMDB to try and find the "best" films those three had been in, cause I haven't seen that much of any of their work, and I think this list might have beaten me
Ashton Kutcher - The Guardian, looks like a generic hotshot rebel in the training acedemy flick, and therefore probably inoffensive, although good might be a push.
Freddie Prinze Jr. - Who I basically know only as Buffy's husband, looking down his list of films, I honestly don't think I've seen any of them, so don't know what he's like as an actor. The best thing on his cv looks like it could be "I know what you did last summer" which face it isn't saying a lot.
Rob Schneider - christ I don't know, Judge Dread?
