“Amateur Night” (*** out of four) was a funny comedy about an out-of-work architect (Jason Biggs) with a new child on the way who in desperation takes a job as a Craigslist driver, only to learn that it’s a job driving a prostitute (Janet Montgomery) and her various friends and clients. Biggs (of “American Pie” fame) has never been better and makes this movie endearing and entertaining, despite its seamy subject matter. Opening phone call scene is especially funny.
