The Great McGonagall is a 1974 British comedy film directed by Joseph McGrath and starring Spike Milligan, Peter Sellers and Julia Foster.

[citation needed] The Great McGonagall was the seventh in a string of flops for Sellers, whose career improved with his next film The Return of the Pink Panther (1975).

"[6] In The New York Times, Richard Eder wrote "The Great McGonagall, which opened yesterday at the Cinema Village, is endearing, and parts of it are lively and hilarious.

"[7] Variety wrote: "The cast of familiar British faces, many in multiple roles, tries hard, but all are done in by a witless script, hodgepodge structure and sledgehammer direction.

Comedians Spike Milligan and Peter Sellers lead with the machetes, carving fun out of a simple-minded man whose verses didn't scan and whose thoughts were banal, but it's the mutual admiration society of the principals that scores its own goal.
