This first entry in the long-running (some would say interminable) British "Carry On" series is at base a collection of motheaten army jokes, albeit served up with freshness and energy. Future Doctor Who star William Hartnell plays Sergeant Major Grimshaw, whose fondest wish is to win the coveted Best Troop Award before his retirement. Alas, this may never come to pass: his newest batch of conscripts include some of the biggest and stupidest foul-ups in military history. Popular comedian-cartoonist Bob Monkhouse and cockney bombshell Shirley Eaton head up the supporting cast, which includes such "Carry On" stalwarts-to-be as Kenneth Connor, Charles Hawtrey and Kenneth Williams. Carry On Sergeant was very loosely based on The Bull Boys, a novel by R. F. Delderfield.
