Before I go to sleep (2014)

[Drunk Monk]

Nicole Kidman has amnesia, the kind where she wakes up not remembering anything each morning. Colin Firth is her husband who reminds her what's up each day. Mark Strong is her covert psychologist who convinces her to record her memories on a phone every night and calls her in the morning to remind her to find it and watch it. It's a fairly well constructed thriller where Nicole shows her naken butt in the very beginning to grab your attention, then acts a wide range of confusion and fear. I guessed the mcguffin but didn't call it out so it doesn't count.
No swordfight but some bloody beating. Not particularly DOOM recommended but not unrecommended either.
