50. The Third Man (1949)
Orson Welles’ Harry Lime gets one of the most famous introductions in cinematic history, but that’s just the tip of the iceberg when it comes to the iconic moments in Carol Reed’s postwar classic.
A penniless writer heads to Vienna at the behest of his old friend, only to discover upon his arrival that his acquaintance is dead, and from there the mystery and intrigue only thickens.
The incredibly atmospheric cinematography, musical score and phenomenal acting performances all combine in a perfect storm of a thriller that remains one of the genre’s finest ever entries.
