Disney's
One Little Indian (starring James Garner, Vera Miles, and Jodie Foster) was mostly filmed in a canyon outside of Kanab, Utah.
The canyon is now owned by a single entity and is home to the very large
Best Friends Animal Society, a no kill shelter*. If you're in the area it is definitely worth a tour (at least one structure was still standing from filming when we were there a couple years ago). It would be a good spot for a fund-raising screening (other movies were filmed in that canyon as well).
*I'm of the opinion that euthanasia is appropriate for unclaimed strays and feral pet species in most situations but this is the best no-kill situation I've ever seen.
