I thought you might enjoy seeing more pix of young Jack Kelly in his pre-Maverick western film days. I guess you could call him a "tenderfoot" at this point. (Just don't call him "Sugarfoot"--that was Will Hutchins. ;->)
It's 22 year-old JK, in what is often listed as his first film as an adult actor, Fighting Man of the Plains (1949). I happened to catch it as it came on TV a few months ago. I'd vaguely remembered reading that JK was in it. However, I was afraid it was going to be one of those "Is that him?" blink-and-you'll-miss-JK movies, like Holiday Affair.
But, I sat down and watched Fighting Man. Luckily, it had an interesting plot and good acting, and--hey, there's JK! (My brother was over and even he noticed when JK suddenly appeared about an hour into the film: "Isn't that Bart Maverick?")
JK plays an uncredited "cattleman" in a couple of scenes. Other familiar western faces in Fighting Man include Victor Jory (who would later co-star with JK in the short-lived Kings Row TV series), Paul Fix, Barry Kelley, Rhys Williams, and, as "Jesse James", a young actor named Dale Robertson.
