what Movies You feel that are great but feel may have not been seen by the general movie goer?

I am doing a write up and have compiled a list of 25 films from silent to foreign. That I feel may not have been seen by the normal movie goer from all age types.

I will only share 3 and then I will share the write up here when I get it done

El norte
The General
God Bless America

I am looking forward to see what you guys come up with and maybe might make me want to go and get the film.
