Bob Hope's and Bing Crosby's final Road movie. Two years after Crosby's death, Hope announced the possibility (in earnest) of doing "The Road to the Fountain of Youth" with George Burns, but nothing came of it.

The seventh of the seven Bob Hope, Bing Crosby and Dorothy Lamour "Road" films. Dorothy Lamour only showed up long enough to help the boys out of a jam and still have enough time left over to get a song in.
