For Your Consideration (2006)

Sporting a massive ensemble cast, For Your Consideration, Christopher Guest's latest exploration of quirky people, is about the filming and promotion of a movie (Home for Purim) that suddenly finds itself abuzz with rumors of Oscar nomination. Specifically, rumors start to sprout up that a cast member is a likely Oscar contender based on observations of the film's production, and then the rumors begin to shift from one cast member to another. First it's Marilyn Hack (Catherine O'Hara), then Victor Allen Miller (Harry Shearer) and Callie Webb (Parker Posey). And suddenly ambition and jealousy infect the set.
Coupled with the rumors is the celebrity what-passes-for-journalism that begins to plague the picture in all its vacuous glory (played up particularly bombastically by Fred Willard) and studio interference (the movie is "too Jewish"), the poison infects everybody, particularly the actors.
I wouldn't call it Guest's best work, though it is certainly entertaining. They story isn't as tight as either A Mighty Wind or Best in Show. It's structured more around glimpses of forces and events going on around the movie production and actors, all drawn into a web. The performances are all excellent with actors brilliantly cast in their roles from washed up actors and addled producers to snarky journalists and weasely agents.
Overall, the movie is good enough to rate a B+.
