Amanda Peet and Ashton Kutcher meet cute by having offscreen sex in an airplane lavatory as they’re flying from Los Angeles to New York. After that it’s all downhill, for them and for us. This interminable contest between two narcissists, stretched out over many miles and years, is supposed to have something to do with romance. Nigel Cole, the British director, also helmed Calendar Girls, but in that case he had a better cast and script to work with. With Kathryn Hahn and Kal Penn; written by Colin Patrick Lynch. PG-13, 107 min. (JR)
