A high school sports hero (Kevin Hart) grows up to become a frustrated accountant, then back into his life comes the obese loser he befriended in school, now a crazy, buffed-out CIA agent (Dwayne Johnson). This has a pretty good laugh quotient as far as big-budget action comedies go, but who came up with the idea of making the pint-size Hart, one of the sharpest comic actors working, play straight man to the giant, ham-fisted Johnson? (Big men are seldom funny onscreen—there’s a reason Chaplin, Keaton, the Marx Brothers, the Three Stooges, Woody Allen, and Hart all stand or stood about five-foot-five.) Amy Ryan lends able support as another CIA agent tracking the Johnson character, who’s gone rogue, and Jason Bateman has two abrasively funny scenes as the former school bully, now a self-righteous Scientologist. Rawson Marshall Thurber (Dodgeball: A True Underdog Story) directed; with Danielle Nicolet and Aaron Paul.
