Over the years, it has been reported many times, with varying specifics, that at some point the audio track was judged unacceptably poor and entirely re-recorded, with a completely different cast dubbing the dialogue. This is just urban legend, apparently extrapolated from the fact that the first feature version cut from the film was reissued, after WWII, in the UK, with a cheaply dubbed soundtrack (the quality of which was then blamed, in a title card following the credits, on "variable atmospheric conditions" in Guatemala during the original filming) - which version then became the one available on TV in the USA, while the full serial languished in the vaults. In reality, this feature was the only time any cutting of this film's footage was redubbed.
