BANGKOK - Actor David Carradine, a born seeker and cult idol who broke through as the willing student called "grasshopper" in the 1970s TV series "Kung Fu" and decades later as leader of an assassin squad in "Kill Bill," was found dead Thursday in Thailand. Police said he appeared to have hanged himself.

The officer responsible for investigating the death, Teerapop Luanseng, said the 72-year-old actor was staying at a suite at the luxury Swissotel Nai Lert Park Hotel.

"I can confirm that we found his body, naked, hanging in the closet," Teerapop said. He said police suspected suicide.

A spokesman for the U.S. Embassy, Michael Turner, said the embassy was informed by Thai authorities that Carradine died either late Wednesday or early Thursday, but he could not provide further details out of consideration for his family.

Carradine came from an acting family. His father, John, made a career playing creepy, eccentric characters in film and on stage. His brothers Keith, Robert and Bruce also became actors. Actress Martha Plimpton is Keith Carradine's daughter.

"My Uncle David was a brilliantly talented, fiercely intelligent and generous man. He was the nexus of our family in so many ways, and drew us together over the years and kept us connected," Plimpton said Thursday.

Carradine was in Bangkok shooting the movie "Stretch," said his manager, Chuck Binder.
