He's Just Not That Into You (2009 Ken Kwapis)

Written by Abby Kohn and Marc Silverstein (both wrote Valentine's Day) deriving material from a relationship advice book by Greg Behrendt and Liz Tuccillo, and interspersed with amusing anecdotes from people with relationship hurdles, e.g. African tribe ('Maybe he forgot your hut number. Or was eaten by a lion.')

Slowly and cleverly introduces the cast and their interrelationships: Ginnifer Goodwin (great), Kevin Connolly, Scarlett Johansson, Bradley Cooper, Justin Long, Jennifer Aniston, Jennifer Connelly, Ben Affleck and Drew Barrymore. We both agreed on the voluptuousness of Scarlett.

Very enjoyable.

if you will get up to this sort of thing in your office...
