Indiana Jones and the Island of the Dinosaurs
It’s Jurassic Park III with old Harrison Ford deepfaked over Sam Neil, his voiced dubbed by an impressionist, and his hat rotoscoped to be brown. Modern technology is toned down as much as possible to make it plausibly seem like the 50s or 60s. This unfortunately means cutting the satellite phone plot. Billy Brennan is now Dr. Jones’s paleontological advisor, since Jones himself obviously can’t fulfill that role.
Certain musical cues are replaced with the iconic Indy theme, but the rest can remain largely intact, as Don Davis masterfully imitated Williams’s signature style. The Jurassic Park theme should probably go, given its close association with the source material.
The island is reframed as a classical lost world that is typical of the Indy series’s genre of origin. Not sure what to do with all the manmade stuff, though. Prior expedition? Soviet research colony? You can’t remove it altogether as it’s in every other scene, including the unskippable runway sequence. The other question is why Jones would be dragged along in the first place.
