11. Rear Window (1954)
A photographer confined to a wheelchair is convinced that he’s witnessed a murder in Alfred Hitchcock’s voyeuristic masterpiece, that takes place almost entirely on a single set.
This being a Hitchcock mystery thriller, nothing can truly be taken at face value, and soon enough layers of doubt are cast upon both the reliability of the photographer’s claims and his own psyche.
The best mysteries cause viewers to constantly change their minds and cast suspicions elsewhere as the plot rolls on, and few movies create that sense of uncertainty better than Rear Window.
