Jim Dale did all his own stunts during the filming. At one point, he was taken to hospital after his arm repeatedly banged against a delivery trolley, causing him to have an emergency operation. The next day, he was back at work doing a stunt where a hammock falls through a wooden floor.
The stunts Jim Dale did when he was an intoxicated Nookey left him with back problems for many years later. The slide down the stairs on a medicine trolley tore a muscle in his left arm, which had to be operated on in hospital. Regardless, he refused to get a stunt double for Nookey's hammock fall, despite Peter Rogers' huge concern.
Although Sidney James (Gladstone Screwer) is first billed, he does not appear until 37 minutes into the film.
This was Jim Dale's last Carry On appearance for 23 years until his return in Carry on Columbus (1992).
