I remember seeing him in
Damnation Alley with George Peppard. I was very disappointed in it because it strayed too far from the original book by Roger Zelazny which I thought, and still do, would make a great Post-apocalyptic film if handled right. He wasn't terrible in it as I recall. I also remember driving through LA in 78 or so and seeing the vehicle from the film sitting in a scrapyard. If I had not seen the movie I would never have known what it was.
