Have you ever rewatched The Hangover and thought, man, these guys are just too fresh-faced and inexperienced to properly party? In the off chance that has ever happened, you're in luck with the trailer for Last Vegas, in which aging stars Michael Douglas, Morgan Freeman, Kevin Kline, and Robert De Niro star as four friends who head to Sin City for one of their bachelor parties. Once there, they are ready to "party like it's 1959," and the Lipitor jokes start flowing like wine.
All told, the preview is pretty cute, mostly because the actors are so beloved and really seem to be having a good time. If anything, it's worth it to watch Freeman discover vodka Red Bull cocktails and the obvious post-vodka Red Bull dancing. Last Vegas comes out Nov. 1, and you can watch the trailer after the jump.
