Highlights include a giant mechanical chess game, gorgeous Mediterranean locations (the movie itself looks beautiful), theme song by The Walker Brothers and of course Elke and Sylva look great in bikinis. Also featuring Steve Carlson,Nigel Green and Suzanna Leigh. I remember seeing this at the drive-in as a kid along with Tobruk (my reason for going) - which also starred Nigel Green. A sequel from 1969 titled Some Girls Do is currently not on video.
Released on DVD in the U.S. by Henstooth Video. The bare-boned DVD is letterboxed at 2:35 to 1, although the print itself looks a little ragged. The best choice is the U.K. DVD release which sports a beautiful anamorphic transfer, vintage interviews and a still collection.
