Film Credits

Odd that the film's credits have "E.P. Lyle, Jr." as the writer of "D'Artagnan of Kansas" (not "F.R. Lyle, Jr.").

Also, TCM's Robert Osbourne and IMDb itself say that Victor Fleming (director of "The Wizard of Oz" and "Gone With The Wind") was the cinematographer -- but the credits which open the film say "Photography by Hugh McClung and Harry Thorpe," neither of which are aliases of Mr. Fleming.

What gives?
