My favourite movies from the 70's, most of which are from the early part of the decade, for some reason.
They are not in any particular order:

1. The last picture show (1971) - directed by Peter Bogdonavich, it's black and white, lauded as the best film since Citizen Kane by some. It's detailed, and lovingly filmed. early appearances by Cybill Shepherd and Jeff Bridges.
2. American Graffiti (1973) - more American nostalgia, from George Lucas this time. Richard Dreyfuss is obviously too old to play a high school kid, but I still love to watch it, and all the music (doo wop and rock 'n' roll sounds great too).
3. Rocky horror picture show (1975) - science fiction, double feature? Brad and Janet? you know the rest.
4. Picnic at hanging rock (1975) - hypnotic Australian movie, about sexual wakening / repression, very evocative classical piano concerto music.
5. Alien (1979) - I like all the Alien films, but this one's the best.
6. Don't look now (1973) - one of the most frightening films I've ever scene, without being an out-and-out horror film (and it has one of the most erotic love scenes, too).
7. A clockwork orange (1971) - incomparable cult movie, valuable source for rock bands searching for a name.
8. Taxi Driver (1976) - directed by Martin Scorsese, it's still shockingly violent, but Robert de Niro is superb.
9. That'll be the day (1973) - not Oscar material, I know, but I love this tale of teenage rebellion and early Brit pop (and I mean 50s an 60s). David Esex looks good, Ringo Starr does the acting, and there are appearances from Billy Fury and Keith Moon.
10. One flew over the cuckoo's nest (1975) - Jack Nicholson in a very powerful story based in a mental institution.:
