Haven't or don't recall seeing that series. I recall the Buster Crabbe 'Flash Gordon' ones. I do remember those and the 'Commado Cody' serials as being one my favorites.
I've seen the Flash Gordon series. This is the first time I've seen his Buck Rogers. Funny....the surface of Saturn looks like the desert Southwest.
We had some of the old Flash Gordon episodes on VHS at one point. What cracked us up most about them (besides the...umm...questionable acting) was the fact that many of the costumes seemed to be recycled from other movies or shows. The good guys (while on a planet) would wear what looked like Robin Hood costumes and the bad guys wore Roman soldier uniforms. And so on and so forth.
