Could I point out one slight error? Gil Perkins was not William Boyd's double in all his Hopalong Cassidy films but in a series of action movies he did for RKO before his "Hoppy" days. Boyd's doubles in the Cassidy series were usually "western types", Cliff Lyons, Ted Wells, Leo McMahon.
Boyd did however call on Perkins's services for the occasional "tricky stunt". A good example being a fine dive from a dam in Riders of the Timberline (1941).Reuse content
