Paul Schrader's 1980 film American Gigolo is a stylish time capsule, an unhurried story about an in-demand paid companion (Richard Gere) who is all but abandoned when he needs help the most. In Showtime's American Gigolo, Jon Bernthal assumes the title role, and the eight-episode adaptation takes the film's structural bones and builds out a standard-issue thriller adorned with bleak themes of child sex trafficking.
