I read somewhere that the very short video clip in the movie “The Big Wheel” where Happy crashes through the fence in flames - was shot at Armscamp. That’s a 50’s movie starring Mickey Rooney where he goes from midget to Indy. I believe the 2 second clip of the crash was someone’s real crash - then Hollywood took over on a set as they tried to free Happy from the burning car. For the record, I remember off the top of my head, Houston Bundy and Alvin Wallace really were killed on that track. I’ll have to check my records, I think there may have been more.

Quick edit: add Paul Camp (1951) and Otto Butler (1946) to that list.
