"The Wizard of OZ"????

I thought the title was "the greatest movie no-one's ever heard of"?

OK, I don't know if these are the "greatest", but here are a few of my personal favorites:

Dark Star (1974) very early John Carpenter film

A Boy and His Dog (1975) very early Don Johnson in a starring role

The Brother From Another Planet (1984)

IMDB 'em to get more details.
