The Double Man beat much of the competition into the Alps, when movies were helping to glamorise skiing holidays. While The Pink Panther had a ski lodge segment, The Double Man anticipates the cable car action and snowy settings of Where Eagles Dare and On Her Majesty's Secret Service. Interesting to note that the director would soon be working on the iconic Planet Of The Apes.
Added to the admirable location work are the international cast. There are no stars besides Yul Brynner, but there are several actors I have a lot of time for. Clive Revill in particular adds a solid emotional punching bag for Brynner. His intense and downbeat performance is in contrast to his usual extroverted and comedy roles. Anton Diffring was too often cast as Nazi baddies, but could easily deliver menace without a uniform. He starred in several classic horror films of the period, like Circus of Horrors and The Man Who Cheated Death. A young Britt Ekland amply provides glamour here, before she broke it big as a Bond girl.
I grew up watching this movie on TV and always tuned in for the cast, the twisty plot and especially the music. It's a little OTT in places but frantically catchy, pumping up the excitement even when there's little of it on screen. The special effects work is subtle and really convincing in selling the central twist...
I'm very pleased to see that at least this is out now on DVD in Germany, with an English language voice track option.
