The climactic scene was filmed at the Great House Pueblo archaeological site.
Scenes were shot on Main Street in Downtown Durango using both the interior and exterior of the famous Strater Hotel.
Set in southwestern Colorado, near Durango, Hermosa Cliffs, and Chimney Rock.
"On the Bus," the play Cannon and Irene are seen exiting, appears to be fictional, but its author and director Phil Proctor is not. He was a founding member of the Firesign Theater, a popular comedy troupe of the 1960s and '70s. The play "On the Bus" may be an homage to Firesign's similarly titled 1971 LP "I Think We're All Bozos on this Bus." Proctor has also enjoyed success as a voice artist.
