8. A Night At The Opera
9. Monty Python And The Holy Grail
10. The Ruling Class
The only (moderately) obscure titles:
'You Can't Take It With You' is a Frank Capra movie, very much in the mold of 'It's a Wonderful Life' but much sillier and less sentimental. Though I do love "It's a Wonderful Life."
'The Ruling Class' is Peter O'Toole playing the son of a British Lord, who thinks he's Jesus Christ. It started out life as a musical, but all but a couple of the songs were removed for the movie, so when they occur, they seem ridiculous intrusions, and just add to the general silliness.
The BBC 'Pride And Prejudice' -- a miniseries I've watched all the way through at least 4 times, most recently last week. The recent movie with Kiera Knightly was OK, but pretty lame in comparison to this one. A more perfectly cast P&P I can't imagine.
16 Candles -- remember back when John Hughes didn't suck?
Speaking of John Hughes: Only The Lonely. Maureen O'Hara! John Candy! Ally Sheedy! The Chicago El!
