I don’t quite understand the point of remaking a European art film as a generic American comedy—especially one as overwrought as Ruben Östlund’s Force Majeure (2014)—but apparently someone felt it necessary. Nat Faxon and Jim Rash’s disenchanting endeavor stars Will Ferrell and Julia Louis-Dreyfus as a married couple, Pete and Billie, on a ski vacation in Austria with their kids. One day, what appears to be an avalanche careens toward the family as they’re enjoying lunch; Billie attempts to protect their children, while Pete grabs his iPhone and runs away, bringing about marked tension between the two. Cowritten by Faxon, Rash, and Jesse Armstrong, the film oversimplifies the complexities of the original, however contrived they might have been, and generally lacks Östlund’s subtlety and plaintiveness. Louis-Dreyfus, who also coproduced, is the best part of this otherwise middling comedy, but even her vexatious zeal can’t save it. With Miranda Otto, Zach Woods, and Zoë Chao.
