Without question, I would put THE WRONG BOX on any list of the ten best movies ever made. Certainly, to my mind, it is the most perfectly conceived and realized comedy to appear in my lifetime (and I have been around for a long spell). All the performances are flawless, but Peter Sellers's Dr. Pratt is, I believe, the best work he ever did on the screen. His characterization is hilariously funny and, at the same time, heart-wrenchingly poignant. It is worth the price of the film simply to see what he does with the kitten and the thermometer (No, not what you expect). I have always suspected that he and Peter Cook improvised their dialogue and these two brilliant satirists display a give-and-take of such high wit and subtlety that it is probably unique in cinema.
An amazing, wonderful, happy motion picture. THE WRONG BOX is a classic.
