A spokesman for the U.S. Embassy, Michael Turner, confirmed the death of the 72-year-old actor. He 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.
The Web site of the Thai newspaper The Nation cited unidentified police sources as saying Carradine was found Thursday hanged in his luxury hotel room.
It said Carradine was in Bangkok to shoot a movie and had been staying at the hotel since Tuesday.
The newspaper said Carradine could not be contacted after he failed to appear for a meal with the rest of the film crew on Wednesday, and that his body was found by a hotel maid at 10 a.m. Thursday morning. The name of the movie was not immediately available.
It said a preliminary police investigation found that he had hanged himself with a cord used with the room's curtains. It cited police as saying he had been dead at least 12 hours and there was no sign that he had been assaulted.
A police officer at Bangkok's Lumpini precinct station would not confirm the identity of the dead man to The Associated Press, but said the luxury Swissotel Nai Lert Park hotel had reported that a male guest killed himself there.
Carradine was a leading member of a venerable Hollywood acting family that included his father, character actor John Carradine, and brother Keith.
In all, he appeared in more than 100 feature films with such directors as Martin Scorsese, Ingmar Bergman and Hal Ashby.
But he was best known for his role as Kwai Chang Caine, a Shaolin priest traveling the 1800s American frontier West in the TV series "Kung Fu," which aired in 1972-75.
He reprised the role in a mid-1980s TV movie and played Caine's grandson in the 1990s syndicated series "Kung Fu: The Legend Continues."
He returned to the top in recent years as the title character in Quentin Tarantino's two-part saga "Kill Bill."
