In between his performances in Dad's Army, Le Mesurier acted in films, including the role of the prison governor opposite Noël Coward in the 1969 Peter Collinson-directed The Italian Job. The cinema historian Amy Sargeant likened Le Mesurier's role to the "mild demeanour" of his Sergeant Wilson character. In 1970, Le Mesurier appeared in Ralph Thomas's Doctor in Trouble as the purser; he also made an appearance in Vincente Minnelli's On a Clear Day You Can See Forever, a romantic fantasy musical.
