Come Play with Me is a 1977 British soft porn film starring Mary Millington and directed by George Harrison Marks. The film's cast list contained many well-known British character actors who were not known for appearing in such films. The film is regarded by many as the most successful of the British sex comedies of the seventies. It ran continuously at the Moulin Cinema in Great Windmill Street, Soho, London for 201 weeks, from April 1977 to March 1981, and is listed in the Guinness Book Of World Records as the longest-running British film. A blue plaque on the former cinema's site commemorates this.
