16. To Kill a Mockingbird (1962)
Unsurprisingly, one of the greatest books ever written was adapted into one of the greatest movies ever made, and Robert Mulligan’s coutroom drama remains as timely today as it ever was.
Message movies with showy performances often devolve into overwrought earnestness and histrionics, but To Kill a Mockingbird is both understated and incredibly powerful.
The perfect balance of weighty emotional and societal subtext against a gripping narrative, and Gregory Peck’s performance has long since become the stuff of legend.
