I have read that in 1940-41 Republic Pictures was negotiating to make a Superman serial, when that fell through they made their classic "Captain Marvel", the flying sequences in that were done with a combination of shots of actor Tom Tyler, stuntman Dave Sharpe and the use of a slightly oversize dummy (later used in the Rocketman/Commando Cody serials, even today those flying sequences hold up. Historians of the B-movies and serials have said Republic had the best special effects, Columbia tended to cut corners-Lois Lane wears the same outfit in all 15 chapters. That said, the 2 Columbia "Superman" serials are pretty enjoyable, they do a good job within their budget limits, the actors are much better than those in a lot of big budget productions, they take their roles seriously. You can watch this as a period piece or as an adventure in its own right.
