robinson crusoe like comedie

ahoy everybody

when I was kid I saw a movie with a guy alone on a island, he finds a huge black rock that looks like a head
he manages to get inside and then, later, he realized that there are cannibals that come to the island once in a while or something

then I remember he got rescued by an old guy and a lady (I think)

then at some time they pass through a volcano or something to escape the island..a mix between robinson and jules verne

my memories are not really clear, but I remember it was really more of an adventure comedy that a real crusoe drama..probably some sort of disney movie

well if it rings a bell to anyone

thanks

nobody ?

The only movies that came to my mind don't really fit your description, unless you confused dinosaurs for cannibals haha. You just said "when I was a kid", but didn't state how long ago that was and there's no age on your profile, so I didn't want to suggest something that was relatively new (both movies I was thinking of were in the last 10 years).
