Kevin Hart kicks off the second year of his box office assault and effort to solidify his status as the next stand-up comic turned mainstream movie star with his version of Hitch. Instead of helping chubby white guys get the girls of their dreams, Hart plays the go-to for grooms in need of best man services. He faces what seems like an impossible challenge when approached by Doug Harris (Josh Gad), who needs not only a best man but also a full seven-man dream team of groomsmen in order to impress his in-laws. Leaving nothing to chance, Hart will follow The Wedding Ringer with a Will Ferrell pairing in a couple of months. Say what you will (and Sony executives certainly did), the guy is making a play for the title of hardest-working man in show business. (Opens wide Friday) (R) Not reviewed
