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.
