I had already written this once, but do not understand how everything was simply wiped away from your memory.
Anyways a bunch of tourists, mainly Americans including a boy of 10-11 years of African origin and a European priest are abandoned by plane on a desert island or anywhere deep inside Africa by vicious head-hunters or smugglers. The boy in search of a safehouse, enters a deserted mansion but finds it filled with lion prides, elephants and other wildlife; but when they all enter it later, they find it empty.
A gruff (American) truck driver, called (something like) Butch becomes their only hope of rescue along with a jungle lass in scanty garb who cannot speak human and rides elephants. In the end, the animals return and help the brave tourists to fight off the smugglers/head-hunters who for some reason have returned to loot/slaughter the former. Butch and small boy opt to remain on the island with jungle lass even after getting a free air ticket.
Finally I saw this movie in the 90s and the movie had an 80s quality picture and shooting technique.
Now kindly save my post and help me find the movie name!
