It's not easy to heap praise on Mel Gibson. His apparent personal conduct and views are completely unappealing and, worse, totally offensive. On screen Gibson started out with a bang in the Mad Max films and was entertaining in the first Lethal Weapon movie, but otherwise his performances and choices of roles have not been very memorable. As a director, I couldn’t slog through his The Passion of the Christ; Man Without A Face was trite; and Braveheart was an overrated piece of hokum. All that aside, it’s easy to declare that his Mayan action adventure film, Apocalypto, is pretty damn brilliant, maybe even a sorta-whacked out masterpiece.

The film takes place in 16th century Central America near the end of the Mayan period, just before the arrival of the Spanish. It’s shot completely in the Yucatan Maya language with unknowns and non-actors, indigenous North Americans. In some ways the film is actually one long, exciting, and very brutal chase scene. Jaguar Paw (Rudy Youngblood), low on his tribe's totem pole, witnesses his tribe being slaughtered and enslaved. He hides his wife, Seven (Dalia Hernandez), and child and goes on an adventure worthy of Playstation. After killing of some of the raiders he is captured by the psychotic Zero Wolf (Raoul Trujillo) and led to the Mayan city, a much more advanced and destructive place than anything the young villager had experienced before. Jaguar Paw manages to escape after much horrific torture and human sacrifices, and is chased as he tries to get back to save his family. It’s a delirious obstacle death course of horror, as he has to make his way through the jungle using all his survival skills to outwit his captors.

As of writing, the tough as nails action flick Dark Of The Sun is still not available in the U.S. on DVD. To see it at home you have to endure an old pan n’ scan VHS edition, which is reportedly edited (for violence) from the original cut that graced cinemas in the late '60s. Also known as The Mercenaries, even with the low quality options, it’s worth watching. Filled with spectacular African locations, cool action, solid performances, and, most importantly, a wildly inventive score by the French composer Jacques Loussier, Dark of The Sun is a lost gem that deserves to be rediscovered.

Less preachy in its mission than more recent films like Blood Diamond, the social statements about race and economic exploitation of Africa are there, but Dark Of The Sun is more concerned with action. Ultra-cool Rod Taylor (The Birds) plays Captain Bruce Curry, a mercenary in the Congo. He is hired to retrieve a load of diamonds deep in the mountains and, while there, rescue a group of white company workers about to be attacked by rebel soldiers (Simbas). Aided by his top man, Sergeant Ruffo (American football star Jim Brown), and a drunken British doctor Wreid (Kenneth More), they put together a team of Congolese soldiers led by a nasty German Nazi officer, Henlein (Peter Carsten). Along the way they pick up a saucy Belgian care worker, Claire, who has some obvious chemistry with Curry (Yvette Mimieux, Taylor’s love interest a decade earlier in The Time Machine) and fight though UN roadblocks, rebel soldiers, and airplanes.

Lean, intense and pictorially spectacular, The Naked Prey made a big impression when I saw it as a teenager in its original theatrical release. My high school buddy Todd McCarthy – today Variety’s chief film critic – saw it with me, and for years he called me “Gampu” in honor of Morrison Gampu, one of its leading native players.

The story is based on a true incident in which a member of Lewis and Clark’s expeditionary party was tracked by Blackfoot Indians in a tribal “run of the arrow.” Actor-director Cornel Wilde’s film transposes the tale to 19th-century Africa:  After the members of his safari are captured and brutally massacred by a native tribe, one courageous member of the party (Wilde) is given a fighting chance, and is released into the bush naked and unarmed, pursued by 10 fierce warriors. In the wild, he is imperiled by human and natural predators.
