Has everyone forgotten that Jungle Cruise has already been a movie, called The African Queen (starring Humphrey Bogart)? Or rather, it was the African Queen that directly inspired 99% of everything in the Jungle Cruise? Of course, it's seen a few decades of plussing since then, so perhaps little of the original remains...
Someone else mentioned Journey to the Center of the Earth, that also was a fantastic movie starring James Mason...
I for one, am still patiently waiting for a Kingdom Hearts attraction...
