Spellbound and The Manchurian Candidate (spoilers)
I found some parallels between those films worth considering:
- two look-alike lead characters - Laurence Harvey and Gregory Peck http://img56.imageshack.us/img56/9554/38mw.jpg
- plot parallels: soldier gets injured in battle, returns home, has to deal with amnesia/repressed memories
- playing cards are a central element of the trauma: seven of club vs. queen of diamonds http://img56.imageshack.us/img56/4959/55ca.jpg
- comparably shot scenes with an armed protagonist threatening an older man who is about to have a milk http://img56.imageshack.us/img56/5757/46pg.jpg
