I remember that in the late 19 60s a secretary in the office I worked in was diagnosed with TB.So it was still an issue when this film was released.The idea in those days seemed to stick sufferers away in a sanatorium for a year to make sure theye didn't infect anybody else.So in this film many of the patients plus some nurses seem sex starved.Particularly Donald Sinden who reprises his Benskin character with a bit too much relish.Attitudes shown in this film are rather outdated and in the case of Houston character unpleasant.
