Another 'name that movie' thread

I saw this not all that long ago, but can’t remember what the hell it was called. In fact, I can only remember one scene, wherein a rather large Native American (or somebody playing one) is talking to a white guy (I think) about poetry. The white guy says he has forgotten everything he has written.

Any clues?

Might it resemble this?

(Fantastic film)

This is a total guess, but ‘little big man’? I thought I vaguely recalled something like that, but it probably isn’t accurate.

Was Dustin Hoffman in it?

That’s it! The Dope rules once again.
