The Warner Bros. Archive program has rolled out a bunch of Johnny Weissmuller jungle movies. It’s mostly Jungle Jim stuff, but there’s also one (Jungle Moon Men) where he plays himself as a jungle expert thanks to all his experience as Jim and Tarzan.
I’ve bought a few collections through the Warner Archive and it’s good stuff. Not a lot of bells and whistles, but the prints and packaging are better than they have to be considering this is the only legitimate way you’re going to be able to own this stuff. Planning on getting some of these.
