Further Up the Creek is a 1958 British comedy film written and directed by Val Guest and starring David Tomlinson, Frankie Howerd, Shirley Eaton, Thora Hird and Lionel Jeffries. It served as a follow-up to Up the Creek (1958), with Peter Sellers not reprising his role because it clashed with the filming of The Mouse That Roared (1959). Frankie Howerd replaced him.
