from the golden period of british film and this have my vote for one of the funny of all time . screen yesterday at my film society to a rapturous audience and i be astonish at how well the comedy have last ( make in 1950 . ) . it be really down to the expert timing and inimitable play from two of the fine actor britain have produce represent margaret rutherford and alastair sim . adapt from a play by john dighton and this farce be briskly handle by director frank launder . the plot be simple represent a ministry mistake billet a girls school on a boys school . i will always laugh when i think of this film .
