Stewart wasn’t even married yet in 1939, when “Destry” was filmed. That sounds like crap. Heaven knows there’s a lot of well-known scandals/secrets about Hollywood and its folk, but there does seem to a huge wave of “made-up” garbage, especially since the internet era started.
Fine, you think he’s great. As far as I’m concerned Hollywood, except for the commerce it has generated, is a Hell hole, always has been, always will be. IMO the whole place isn’t worth the sweat from between my thighs. If Stewart was a great man, it wasn’t anything he did in the motion pictures that caused it.
