Impressed by his massive...um, chest and biceps, Willson signed him on, gave him one of his patented name changes -- to Cal Bolder -- and got him a minor role in the Anthony Quinn-Sophia Loren Western Heller in Pink Tights (1960).
Bolder claims that he was on the force for 14 years, and left to make movies in 1960. That would mean he got through college and the Marine Corps and became a cop by age 15. One of the many problems with Cal's biography.
Here he plays "muscular thug" Ingo Lindstrum on The Man from U.N.C.L.E.
Top Beefcake Horror Movies of the 1960s, a gay subtext-camp classic that gives you what it advertises: legendary outlaw Jesse James (John Lupton) and his wounded buddy Hank (Cal Bolder) go to the spooky castle of Maria Frankenstein, the Baron's daughter or granddaughter. She finds Hank the perfect subject for her experiments, and turns him into a zombie named Igor (get it?).
After playing a trapper on a January 1968 episode of Cimarron Strip, Bolder retired and moved to Royal City, in rural eastern Washington.
A final problem: was he gay, other than the casting couch?
His internet biographies don't mention anything about a wife or kids, but I doubt that a gay man would leave Los Angeles for the wilderness. I found an obituary for a "Billie R. Craver" of Royal City, Washington (1931-2006). Maybe his wife? And a Dain Craver, who runs an orchard, CraveOrganics. Maybe his son?
