David Letterman has a much stranger sense of humor than he normally gets to express on his own show. As offbeat as he can be, I first realized we had matching taste in movie comedies when he raved about One Night at McCools a few years back — a movie that got panned by most critics. I ignored the reviews, took Letterman’s advice, and discovered a dark twisted gem. Unlike that sycophant on NBC, Dave doesn’t praise a movie unless he genuinely likes it, so last night’s interview with Seth Rogen has me really looking forward to Observe and Report, in theaters April 10th. Letterman on Observe and Report: “It’s one thing after another, so carefully crafted as to be extreme and bizarre to the point where you start laughing, and you can’t help yourself. And every little thing, you think, ‘Oh they wouldn’t put that in th– Oh they did.’ And before you know it, you can’t stop laughing.” Red and trailer for Observe and Report, after the cut.
