Even in this enlightened era, female buddy movies are far and few in between — so it’s a pleasure to have two top comediennes join forces to tear up the big screen with outrageous bits and wild shtick. It’s a great concept picture: Take sassy, foul-mouthed Melissa McCarthy and slapstick-savvy Sandra Bullock and cast them as a boundary-busting Boston cop (McCarthy) and a straight-laced FBI agent (Bullock), throw them on a typical crime case (they join forces to bring down a ruthless drug lord), and watch the sparks — and laughs — fly. Needless to say, Bullock’s by-the-book procedures clash with McCarthy’s nasty and violent style of police work, but the pair eventually learn to work together and bring down the bad guys. Think “Rush Hour” with women. This is one funny movie. Sequel anyone? (Actually, there are rumors of a “Heat 2” in the works). Extras: Commentary, bloopers, alternate scenes, behind-the-scenes featurettes. Vitals: Director: Paul Feig. Stars: Sandra Bullock, Melissa McCarthy, Demian Bichir, Michael Rapaport, Marlon Wayans, Kaitlin Olson. 2013, CC, MPAA rating: R, 117 min., Comedy, Box office gross: $156.392 million, Fox.
