Two Robert Osborne comments about this movie: most of the acting is done in front of projected scenes from the exotic locales that were visited. The director, Tay Garnett, had taken extensive footage of a vacation cruise around the world a year or two before, and had talked the studio into letting him use the footage in this movie. Second, as part of the plot of this movie Joan Bennett dyes her blonde hair brunette in order to conceal her identity. She had always played blondes up until this point and ever after played a brunette.
Familiar face: the San Fransisco police commissioner is played by Thomas Mitchell, who was Uncle Billy in It's a Wonderful Life.
