A pair of second-rate Chicago lounge singers witness a mob murder and hide out as drag queens in West Hollywood. Hijinks ensue. “Connie and Carla” (2004) is pretty much that simple but it actually isn’t half bad. I always enjoy Nia Vardalos doing her vulnerable, star-crossed thing. A lot of the acting is schticky, but drag queens can get away with it. David Duchovny looks completely uncomfortable throughout as a drag queen’s straight brother (It’s either brilliant acting or a case of “why am I in this movie?”). Unfortunately, the plot completely derails into a sloppy mess of an ending.
