The Girl with the Dragon Tattoo (2012)

Long before Daniel Craig stole the show as Benoit Blanc in the whodunit hit Knives Out, he was involved in a different (and significantly darker) story.

The US adaptation of the best-selling Swedish book series won an Oscar for best editing and nabbed another four nominations.
