"The Big Town" has an unpersuasive story, flat performances, and an overly slick look. Matt Dillon never convinced as the small-town kid who sets off to Chicago to be a big-time professional gambler, nor is the gambling syndicate trope convincing. Several much more accomplished actors (Lee Grant, Bruce Dern, Tommy Lee Jones, and Diane Lane) are wasted playing one-dimensional characters under uninspired direction.
