In the dysfunctional family tradition of Dan in Real Life, Little Miss Sunshine, Pieces of April, The Squid and the Whale, etc. newbie filmmakers Mark Poirier (he wrote it) and Noam Murro (he directed it) assemble a talented cast and give them plenty of witty lines to chew over. Dennis Quaid is a widowed college professor who's given up on life. At home, his daughter (Ellen Page from Juno) is an overachieving Young Republican, and his son is trying to avoid his crazy clan altogether. Into this mass of unresolved issues comes ne'er-do-well brother Thomas Hayden Church and possible love interest Sarah Jessica Parker. Predictable, but never wholly contrived, Smart People is a clever, gray-toned dramedy aimed at the same sort of grad-school audiences who chuckled and winced their way through Sideways.93 minutes R.
