The seventh Road comedy, after a lapse of seven years, takes the boys on a haphazard trip to a planet called Plutonius, though this only happens as a climax to some hilarious adventures in Ceylon and Hong Kong.
It’s almost useless to outline the plot. But it involves Crosby and Hope as a couple of flop vaudevillians who turn con men. Somewhere along the line, Hope loses his memory and that, in a mysterious manner, leads them to involvement with a mysterious spy (Joan Collins) a secret formula and a whacky bunch of thugs called the Third Echelon, led by Robert Morley.
The script is spiced with a number of private jokes (golf, Hope’s nose, Crosby’s dough, reference to gags from previous Road films) but not enough to be irritating. Major disappointment is Joan Collins, who though an okay looker, never seems quite abreast of the comedians. Lamour plays herself as a vaude artist who rescues the Crosby-Hope team from one of their jams.
As guest artists, Frank Sinatra and Dean Martin help to round off the film. David Niven appears for no good reason, while the best interlude is that of Peter Sellers. He plays a native medico, examining Hope for amnesia and it is a brilliantly funny cameo.
