"Kung Fu" and "Kill Bill" actor David Carradine was found dead Thursday in a Bangkok hotel room, his manager told FOX News.

According to police, the 72-year-old actor appeared to have hanged himself.

The officer responsible for investigating the death, Teerapop Luanseng, said Carradine 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.

Chuck Binder, Carradine's manager, said the actor was staying in the Thai capital while shooting a movie called "Stretch." When a producer went to his luxury hotel room, he learned that the actor was dead, Binder said, adding that the cause of death is still "under investigation."

Carradine's rep, however, said the death was accidental, telling celebrity new site TMZ, "We can confirm 100% that he never would have committed suicide. It was an accidental death. Everybody is in shock."

According to Thai Newspaper, The Nation, Carradine had been staying at the hotel since Tuesday but could not be contacted after he failed to appear for a meal with the rest of the film crew on Wednesday.

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.

Police said Carradine's body was taken to a hospital for an autopsy which would be carried out Friday.

A statement on behalf of his family has yet to be released, but Binder called the death "shocking and sad ... He was full of life, always wanting to work ... a great person."

But despite an enthusiasm for his work, the actor had openly discussed his battle with suicidal thoughts. In a 2004 interview, Carradine said: "I remember one time sitting at the window of the third or fourth floor of the Plaza Hotel for about an hour, thinking about just tipping off."

He also said he had considered shooting himself.

"Look, there was a period in my life when I had a single action Colt 45, loaded, in my desk drawer. And every night I'd take it out and think about blowing my head off, and then decide not to and go on with my life. Put it back in the drawer and open the laptop and continue writing my autobiography or whatever. But it was just to see."

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.

One of his prominent early film roles was as singer Woody Guthrie in Ashby's 1976 biopic "Bound for Glory."

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."

The character, the worldly father figure of a pack of crack assassins, was a shadowy presence in 2003's "Kill Bill — Vol. 1." In that film, one of Bill's former assassins (Uma Thurman) begins a vengeful rampage against her old associates.

In "Kill Bill — Vol. 2," released in 2004, Thurman's character comes face to face again with Bill himself. The role brought Carradine a Golden Globe nomination as best supporting actor.

Bill was a complete contrast to his TV character Kwai Chang Caine, the soft-spoken refugee from a Shaolin monastery, serenely spreading wisdom and battling bad guys in the Old West. He left after three seasons, saying the show had started to repeat itself.

After "Kung Fu," Carradine starred in the 1975 cult flick "Death Race 2000." He starred with Liv Ullmann in Bergman's "The Serpent's Egg" in 1977 and with his brothers in the 1980 Western "The Long Riders."

But after the early 1980s, he spent two decades doing mostly low-budget films. Tarantino's films changed that.

"All I've ever needed since I more or less retired from studio films a couple of decades ago ... is just to be in one," Carradine told The Associated Press in 2004.

"There isn't anything that Anthony Hopkins or Clint Eastwood or Sean Connery or any of those old guys are doing that I couldn't do," he said. "All that was ever required was somebody with Quentin's courage to take and put me in the spotlight."

One thing remained a constant after "Kung Fu": Carradine's interest in Oriental herbs, exercise and philosophy. He wrote a personal memoir called "Spirit of Shaolin" and continued to make instructional videos on tai chi and other martial arts.

In the 2004 interview, Carradine talked candidly about his past boozing and narcotics use, but said he had put all that behind him and stuck to coffee and cigarettes.

"I didn't like the way I looked, for one thing. You're kind of out of control emotionally when you drink that much. I was quicker to anger."

"You're probably witnessing the last time I will ever answer those questions," Carradine said. "Because this is a regeneration. It is a renaissance. It is the start of a new career for me.

"It's time to do nothing but look forward."
