Vince Vaughn is hilarious, I feel like he hasn't made anything really good in at least 5 years, since 'The Break Up', maybe he's just been picking bad scripts, he still shines in whatever part he plays, but the overall movies have been pretty mediocre to awful. This looks ok, La Times review was fairly promising. Maybe I'll see it.
Vince Vaughn's funniest roles were in 'Made', and 'Wedding Crashers', imo.
