Aspiring writer Jeremy Lloyd was working as a travelling salesman of rust-proof paint in the late 1950s when he wrote a story called 'What a Whopper' about a Cockney youth who runs tours to see the Loch Ness monster. After delivering paint near Pinewood Studios, he pitched the script to studio chief Earl St John, who bought it.

Freddie Frinton was famous for his comic drunk personna which he does in this film. Not only does it jar decades later, but he drives from London to Loch Ness in Scotland drunk too.
