amazed at the Sky Bridge (stone archway) scene
There is a scene early in the movie where Burt Lancaster's character is traveling through Kentucky, and we see him come through a big stone archway. That arch is Sky Bridge, one of many stone arches to be found in the Red River Gorge recreation area in Kentucky.
I had the pleasure of visiting Sky Bridge recently. It's a short hike down to the opening of the arch. But there's sloped rocky terrtain all around it. It amazes me the lengths they must have gone to get a movie camera down there. I'm not too knowledgeable about film equipment, but I would have thought in those days they would have only had those large bulky sorts of cameras. And they did all that just for one short scene.
Incidentally, I don't like the movie that much in terms of story and characters. I didn't think it really worked. But some of the backstory behind making it is interersting. It was actually mosly filmed in Rockport, Indiana (which looks enough like Kentucky). But the scene I refer to above was clearly filmed at Sky Bridge in Kentucky.
