Paul Rudd took time off from preparing to enter a Big Lebowski costume contest, apparently, to film Our Idiot Brother, a fairly mild, lightweight comedy that pretty much sticks to the normal conventions.
He's a lovable fuck-up, you see, who, after being thrown out by his girlfriend (the suddenly omni-present Kathryn Hahn), must spend time with his three successful sisters, who are all played by hot actresses that look nothing alike. They're Elizabeth Banks as an icy, career-minded journalist, Emily Mortimer as a stay-at-home mom who is married to a sleazy documentary filmmaker played by Steve Coogan, and Zooey Deschanel as a free-spirited aspiring artist who dates Parks And Recreation's Rashida Jones, another stunningly hot actress who, in typical movie fashion, is somehow supposed to appear kinda hideous because she wears flannel and thick glasses sometimes.
Anyway, to make a long story short, Rudd "wreaks havoc" on their lives, mostly by unknowingly making his sisters (and their partners) aware of their awful behavior and by sometimes just flat out benignly telling the truth to people who have been terribly deceived for a long time anyway.
I didn't find the movie to be especially funny, really. And I didn't really give a shit about anyone's problems or what happened to them. But it didn't piss me off too much, I guess... it mostly just kinda felt like a mildly agreeable 2 hours at the movies. So there's that.
