Peter Sellers refers to the "manager of the Kirkintilloch distillery" you couldn't even buy a bottle of beer when this was made!! It was a "dry" town, eight miles out of Glasgow.
In this, his film debut, Peter Sellers appears in two credited roles (as well as a third brief appearance during Harry's dream sequence). This would become a trademark of Sellers' film career including such titles as Dr. Strangelove and The Mouse that Roared.
