It's terrible to think that Peeping Tom, one of the best films of the '60s, was also the one that ended its director's career. Michael Powell's grim meditation on a London-based serial killer (played by a perfectly cast Carl Boehm) was met with distain upon its original release, but has since been reappraised as a masterpiece of British cinema. Go figure. Unveiled the same year as Alfred Hitchcock's seminal work Psycho (what a year for horror films, huh?), the conceit driving Peeping Tom depicts the life of a disturbed murderer named Mark Lewis, who gets his kicks from filming his victims using a portable character - all women - to capture their dying expressions as he brutally murders them. As both an exploration into the mind of a serial killer and an unforgettably freaky entertainment to boot, Peeping Tom is bonafide triumph. You can't shake this one off, and - all these years later - it feels bold and progressive in ways other movies simply don't.
