Sylvester Stallone says he and his "Rambo" sequel movie crew recently witnessed the human toll of unspeakable atrocities while filming along the Myanmar border.

"I witnessed the aftermath - survivors with legs cut off and all kinds of land-mine injuries, maggot-infested wounds and ears cut off," Stallone told The Associated Press in a phone interview Monday. "We hear about Vietnam and Cambodia and this was more horrific."

The 61-year-old actor-director returned to the U.S. eight days ago from shooting "John Rambo," the fourth movie in the action series, on the Salween River separating Thailand and Myanmar, formerly known as Burma.

Stallone said he was in Thailand for six months, most of it along or on the river.

"This is a hellhole beyond your wildest dreams," Stallone said. "All the trails are mined. The only way into Burma is up the river."
