The acting nebbish populating this comedy caper are ill-equipped for director Brett Ratner's persistent but ever-inadequate action movie propensities. At the same time, Ratner and (count 'em) four credited writers extract comic ore from their cast with the precision of a dragline. The result is a movie with an identity crisis whose edgiest trait is its stupefying dullness. Josh Kovacs (Ben Stiller) is building manager for a Manhattan high-rise whose employees lose their pension to a Ponzi scheme run by Madoff doppelgnger Arthur Shaw (Alan Alda), the tower's penthouse occupant. Once the fed's case against Shaw starts crumbling, Josh and four co-workers (Matthew Broderick, Casey Affleck, Michael Peña and Gabourey Sidibe), aided by a motor-mouthed ex-con (Eddie Murphy), conspire to rob Shaw's condo of ill-gotten loot. As the hole-ridden plot staggers from one half-baked scene to another, its stars are left to yammer and mug for the camera in a desperate group salvage operation.
