There are about a thousand funny things happening in In a World.
First, theres the insular community in which its set: voice-over artists competing to be the next Don LaFontaine, the guy who practically patented the phrase, In a world ... at the beginning of movie previews of coming attractions.
As in such Christopher Guest movies as Best in Show and Waiting for Guffman, In a World is set in a tiny back-bitey community of people, and their sense of their own importance is hilarious as they compete for the gig doing trailers for a Hunger Games-like quadrilogy an idiotic word they use over and over to increasing comic effect.
Lake Bell, who wrote the quick-witted script and directed, plays voice-over wannabe Carol. Her pompous dad (Fred Melamed) resents her attempts to invade his professional territory, and Carol and her neurotic sister, Dani (Michaela Watkins, who is gut-bustingly funny), resent each others choices but not as much as they resent their fathers relationship with a dim-witted woman who is younger, dumber and blonder than they are.
A well-disguised romantic comedy involves Carols fling with a vain voice-over superstar (Ken Marino), while two colleagues who seem more suitable (played by wry Nick Offerman and sweet-natured Demetri Martin) lurk in the background. For good measure, Dani and her husband (Rob Corddry) weather a rough spot in their happy, somewhat crabby marriage.
The film is smart about relationships in a world where starved romcom fans have been waiting all summer for a movie just like it.
