Bright script and brisk direction conceal the stage origin [from the play by John Dighton]. The story is given a wider canvas and isn’t wanting in action. In fact, the pace never lets up and one hilarious farcical incident only ends to give place to another.Setting of the film is a college for boys, to which, as a result of a slip at the Ministry of Education, a girl’s school is evacuated. The story builds up to a boisterous climax in which the principals are trying to conceal the real situation from visitors to the college. There is no shortage of laughs, but the joke is a little too protracted and wears thin before the end. It’s an ideal vehicle for Alastair Sim as the harassed headmaster, while Margaret Rutherford admirably suggests the overpowering headmistress.
