Almost all movie ideas turn to crap in OFP. I would like to see it, but I don't see Fonda and the other dude...(haven't watched the movie in awhile) shooting rednecks. Also, I don't want to watch a 20 min cutscene...
Though the right addons are out there, I think you'd be better off working with some biker gang idea and not the awesome film Easy Rider was, but hey that's my opinion.
edit: hey i remembered the other guy... Dennis Hopper
