Lord High Vizier of Nowt
We had it on one of those "Sci-Fi Classics" [sic] DVD collections of poor quality copies of public domain stuff. The serial format is pretty wearying when watched all at once.
...and pretty incomprehensible when edited into a 'feature' as so many of them were. Several hundred minutes of action condensed into 80 or so minutes. The only one I can remember seeing that didn't look fecking awful was The Lost Jungle (1934) which played like a run of the mill jungle adventure yarn; it was only after seeing it I found out it was a 200+ minute, 12 part serial trimmed to a 68 minute run time.
