Gunmen of the Hollow Earth

In "Hollow Earth," a South American hunting expedition for the infamous outlaws Butch Cassidy and the Sundance Kid takes a perilous turn, trapping Doc Holliday, the Earp Brothers, and Native American gunslinger Lone Crow in a hidden world beneath the Earth's surface. To survive, they form a fragile alliance against fierce female warriors and the terrifying prehistoric creatures that inhabit this jungled realm. As their ammunition dwindles and treachery looms, they hasten to find a passage back to the surface, all while being pursued by a relentless gang of bandidos.
