In the days before the IMDB, when some joker swore that rival gang-leader Billy Boy was actually played by Jimmy Page, there was no way to know for certain. (After all, it wound up being true that George Harrison financed Monty Python's Life of Brian.) It turns out that the would-be rapist in the derelict casino whose only line is "let's get 'em boys!" is actually a man named Richard Connaught. His other acting job was as "Second Removal Man" in the anthology horror film Tales That Witness Madness.
A Clockwork Orange's use of light classical hits against striking, dark images was absolutely revolutionary in 1971. The conclusion to Giochino Rossini's The Thieving Magpie Overture is an agreeable, dainty little ditty meant to ensure that all society folk who wandered into this movie would drop their monocles in shock.
