El CID (which was on TV just last Saturday),
Spartacus,
The Magnificent 7 films,
American Graffiti.

And for some not so old but good foreign films (if you don't mind subtitles!):
Jean De Florette & Manon des sources (Manon is the 2nd part to JDF),
Le Bossu,
Curse of the golden flower (amazing cinematography, costumes & colours),
Red Cliff.

I've got tons of movies at home, but most are more recent films.
