Well I am getting a good list to check out. I think these movies that are off the main stream are art. Most movies are about entertainment and money, not art. I do enjoy finding A list actors in an obscure cult flick that they never talk about. It gives them at least some respect as an artist.
Silent Running
Harold and Maude
Escape from New York
My dinner with Andre
Journey to the center of the earth: with James Mason and a very young Pat Boone.
Crack in the world: scientifically outdated about 5 minutes after it was made.
Petrified forest: young Humphrey Bogart.
We’re no Angels: once again Humphrey Bogart and very, very funny.
1776
I haven’t really watched movies recently, other than a trailer of 500 MPH Storm. I guess all of the movies made by Don Hertzfeldt are real good, especially Rejected.
Anything by the Marx Brothers… famous for their one-liners and instrumental talents (classically-trained to orchestral performance level), as well as their slapstick comedic tomfoolery.
