In the days before political correctness reared its ugly head, boys were boys and girls and girls, and ne'er the twain should meet - except for St. Trinian's where small girls were boys, at least in their behaviour, and large girls were rather pretty, in Sabrina's case voluptuous. The main characters were all well drawn with a splendid supporting cast and all very British. Alastair Sim was perfect as the headmistress, George Cole was the Cockney geezer, Joyce Grenfell the ever spurned policewoman while Eric Barker as Culpepper Brown and Richard Wattis as Bassett were truly superb archetypal education ministers. As for Terry-Thomas - well? Even a coach driver could be posh in those days! Stiff upper lip what, even with St. Trinian's on board. All good clean fun which had family audiences flocking to the local cinema. What a pity they don't show films like this any more on television because they beat the modern rubbish hollow for entertainment value.
