Stodge City is in the grip of the Rumpo Kid and his gang. Mistaken identity again takes a hand as a 'sanitary engineer' named Marshal P. Knutt is mistaken for a law marshal. Being the conscientious sort, Marshal tries to help the town get rid of Rumpo, and a showdown is inevitable. Marshal has two aids—revenge-seeking Annie Oakley and his sanitary expertise.
Carry On Cowboy is a 1965 British comedy Western film, the eleventh in the series of 31 Carry On films (1958–1992). It was the first film to feature series regulars Peter Butterworth and Bernard Bresslaw. Series regulars Sid James, Kenneth Williams, Jim Dale, Charles Hawtrey and Joan Sims all feature, and Angela Douglas makes the first of her four appearances in the series. Kenneth Williams, usually highly critical of all the Carry on films he appeared in, called the film "a success on every level" in his diary, taking pride in its humour and pathos. The film was followed by Carry On Screaming! (1966).
