"The serial was released on home video in the late '80s in a heavily edited format that removed the offensive racial content. Dan Scapperotti, a reviewer for the magazine Cinefantastique, commented: “The revisions aren’t surprising when you consider that Columbia is now owned by Japan’s Sony Corporation. It appears that some of Daka’s operatives escaped Batman’s justice and were rewarded with positions at the new George Orwell department at Columbia. No doubt we can expect to see David Lean’s Bridge on the River Kwai reissued as the story of a joyous Anglo-Japanese cooperative construction job interrupted by imperialistic American terrorists.” Sony released the serial on DVD in October 2005 in an unedited version, with the exception of Chapter 2, which is missing its “Next Chapter” sequence and a shot of the villains listening to Bruce and Linda’s conversation instead of Robin being angry.
The image and sound quality of Columbia’s two-disc set is varied. The first episode is an upscale of the previous VHS transfer: very grainy, slightly cropped off, and with too high contrast in some scenes, such as the first establishing shot of Batman sitting at a desk amid a bunch of bats in the Bat Cave. The rest of the episodes were restored as much as possible, with the result being solid pictures and good sound.
Mill Creek Entertainment released in February 4, 2014 Gotham City Serials, a two-disc DVD set that contains both the 1943 serial and the 1949 Batman and Robin serial.
The serial was also released on home movie formats in the 1960s and 1970s:
The 1960s: A silent abridged version. The complete serial was edited into six chapters (available in 8mm and Super-8) running 10 minutes each. A seventh three-minute reel titled “Batman’s Last Chance” with action scenes was also issued.
The 1970s: The complete 15-chapter serial (in its original unaltered format) was released in a Super-8 Sound edition."
After reading all this from Wikipedia I was wondering, where I could find a complete Version of Batman 1943?
