Se7en

David Fincher's 1995 neo-noir thriller pairs Brad Pitt and Morgan Freeman as detectives tracking a killer using the seven deadly sins as a blueprint, shot in perpetual rain-soaked darkness that cost $33M and earned $327M — a 9.9x return that is faster than the average multiplier of #1 Psycho (62.5x) but still impressive. The haunting question 'What's in the box?' echoes through pop culture three decades later, and its 8.6/10 IMDb rating is 0.4 points lower than #2 Rear Window's 8.4. Se7en's devastating finale remains one of cinema's most shocking, underpinned by a 83% Rotten Tomatoes score.
