Take one “British Baking Show” and add a cup of Christopher Guest improvised mockumentary, a lot of processed food products, a gallon of ambition, romantic complications, sibling rivalry, and a muffin-head-wearing mascot, and let it marinate for a decade and you’ve got “Cook-Off,” a very funny movie made ten years ago but just now being released in theaters. Its stars include Melissa McCarthy, Niecy Nash, Diedrich Bader, and the late Marcia Wallace. It has all the ingredients for a tasty little entertainment.

Like Christopher Guest’s “Best in Show,” this is a story about middle-class Americans passionately seeking to outdo each other, with a gallery of brilliant improv actors making small fights into a cutthroat competition. It takes place at a Pillsbury Bake-Off-style cooking contest with co-screenwriters Cathryn Michon and Wendi McLendon-Covey playing sisters Sharon and Pauline Solfest, who work together selling sex toys to married Lutheran women at home but have both qualified for the competition. Sharon (Michon), whose many different hairpieces are a hoot, is outgoing and outspoken, engaged to Lars Hagerbakke (Gary Anthony Williams), who is a bit confused about his identity, in part because he is a black man adopted by a white Swedish family. Her sister Pauline (McLendon-Covey) is withdrawn and shy, but don’t count out her creamed corn.

Also in the competition are Ladybug Briggs (Niecy Nash), the wheelchair-confined mother of a part-time preacher, the very, very pregnant Patty (Romy Rosemount), and the first-ever male contestant (Dietrich Bader), who just happens to be engaged to a former contestant who, after making it to the finals three times, is no longer eligible to compete, raising questions about the legitimacy of her fiance’s entry. Amber Strang (McCarthy with her real-life husband Ben Falcone) arrives too late but wear everyone down with their elaborate explanations and get to compete as well. And a hard-driving realtor is the Mama Rose of the competition, pushing her daughter like she’s selling a house. Meanwhile, Gavin McLeod and Marcia Wallace play themselves as the celebrity judges and the sponsor’s mascot, the guy with the muffin head, is wandering around contributing to the sense of happy (at least for us in the audience if not the characters) chaos.

Parents should know that this film includes strong language, some crude sexual references and drinking.
