I can't say I know much about many of the movies from back then and even less about the tv shows. I mean I am sure you have had movies or shows about dreams or fantasy enviroments but not one that sort of takes a realistic look at a altered timeline or realisitc by 40's standards, anyways. Jason
Depends on how you define that. IAWL is a riff on Dickens' "A Christmas Carol" which I believe had already been done as a film.
Well, you have the Wizard of Oz from 1939 for the classic but which had silent adaptations as early as 1910. EDIT: Ah shit, I see where that's not what you meant...
Yep. "A Christmas Carol" directly addresses the issue of alternate futures and timelines: "Are these the shadows of the things that Will be, or are they shadows of things that May be, only? Men's courses will foreshadow certain ends, to which, if persevered in, they must lead, but if the courses be departed from, the ends will change. Say it is thus with what you show me!" EDIT: Looked it up. There were many silent and talkie versions of A CHRISTMAS CAROL predating IAWL. https://en.wikipedia.org/wiki/Adaptations_of_A_Christmas_Carol#Film
