Here is a photo I found of Ted White (for the uninitiated, the stuntman who portrayed Jason in Part 4) and the man he doubled for, John Frickin-Wayne, aka The Duke. As you can see The Duke is a HUGE man. Ted White, who in his prime stood around 6'4" looks like a kid next to him. This photo is probably from the late 1950's or early 1960's. Ted White has appeared at conventions to sign autographs for fans, despite being 84 years old (57 when he portrayed Jason in late 1983). That makes him pretty awesome.
