Seconds (1966)

Frankenheimer's Seconds was shot by James Wong Howe, and it's innovative and fascinating and completely unnerving. The film itself didn't really make sense to me – I just didn't get why the main character was so tortured and upset by what he'd done. I didn't understand why he couldn't make a go of his new life, or, indeed, why he thought he needed a second new face in order to try a third time. But Rock Hudson is a revelation in this, and the film's ending is totally great. Incidentally, Teshigahara's The Face of Another (released in the U.S. in 1967), which works with similar themes, came out in Japan around the exact same time as Frankenheimer's film.
