When he became director and worked on the Carry on films he always had a tight shooting schedule which never exceeded 6 weeks. Despite this he had a great sense of fun often playing tricks on the cast such as filling Joan Sims' glass with gin instead of water in Carry on Regardless and hosing down the beauty contestants in Carry on Girls when they were only expecting a damping down from sprinklers.
