Enjoyable if dated, they are still using punch cards to program their computers!, espionage thriller with a solid cast. Caine is cool as ice as the reluctant protagonist casting a jaundiced eye on all the shenanigans going on around him. Francoise Dorleac is a lovely mystery woman although her character seems to vanish at several key points in the film when it feels like she would be there. This might be because she was killed in a traffic accident while the picture was still filming necessitating a rethinking to still make her completed work usable. She's quite magnetic, her resemblance to her sister Catherine Deneuve is striking, and her death cut short a career that was already very successful in France and was starting to expand worldwide. Ed Begley also stands out, having a great time as a crazy old coot. Subtle he ain't but memorable for sure.
