The Viper is a 1938 British slapstick comedy film directed by Roy William Neill and starring Claude Hulbert, Betty Lynne and Hal Walters. The film was a sequel to the previous year's very successful The Vulture, with Hulbert and Walters reprising their roles as hapless private detective Cedric Gull and his sidekick Stiffy respectively. Lesley Brook also features in both films, but in unrelated roles. Directorial duties passed to Neill as Ralph Ince, the director of The Vulture, had been killed in a road accident shortly after the film's release.
