The ending is obvious a mile off, the riff on crime witnesses hiding out in a subculture ghetto is old, but there is still some entertainment to be had from this charming bit of fluff. Toni Collette is an absolute chameleon of an actress; she can pull off the “ugly” nerd and the gorgeous femme fatale and makes a credible drag queen, too, even though the audience does know she’s a woman playing a man dressed as a woman. Nia Vardalos less so. But it’s fun watching them mug and prance their way through a whole lot of show tunes, fight bad guys in the midst of a floor show, kiss David Duchovny and squabble like sisters. Cute.
