In case you haven’t yet seen how Ivan Guerrero, the guy who lashes clips of old movies and trailers together to create “Premakes” — trailers for movies as if they were made many years before they really were — did one for Pixar’s “Up” as if it were a typical live-action Disney movie from the 1960’s, here it is:

Spencer Tracy as Carl, Kirk Douglas as Charles Muntz, in the 1965 live action version of “Up!” that never existed.

There are other “Premakes” that have gotten a half-million views each, including “The Empire Strikes Back,” 3-D 1950’s version (it actually looks more 1940’s or even 1930’s, probably because he used Flash Gordon and Buck Rogers clips, but low-budget 1950’s movies often had that look as well):
