this film be make thirteen year before i be bear but i still think it be the witty and dotty and most harmless piece of fun ever make . it simply could not go wrong with the cast of superb british character actor it boast . where to start . alastair sim peerless while margaret rutherford ditto while the wonderfully alkward and innocent gossage and play to perfection by the imperious joyce grenfell . the caddish victor hyde brown ( a guy middleton special ) and the rest of the staff sum up post war middle class england to a tee . the humour be sometimes obvious and but it be of that special ealing variety and be never offensive . i have watch this film more time than i care to remember and still laugh like a drain at the antic every time . the storming of the dorm occupy by the girl school and the magnificently plan but ultimately doom twin tour of the school and the chaotic end involve the arrival of a third school to add to the anarchy and be priceless . it an old cliché i know and but they really do not make them like that anymore . how i wish they do . if you haven not see it and please do and you would not be disappoint .
