David Carradine believed he delivered "some of my best work" in Kill Bill
Kill Bill and Kung Fu star David Carradine has been found dead in a Bangkok hotel room on Thursday.
Thai police told the BBC a hotel maid found the 72-year-old naked in a wardrobe with a cord around his neck and other parts of his body.
The US star was in Thailand filming his latest film, Stretch, according to his personal manager Chuck Binder.
Mr Binder said the news was "shocking", adding: "He was full of life, always wanting to work... a great person."
Police said the actor's body was found in a suite at the 5-star Swissotel Nai Lert Park hotel.
A US embassy official confirmed the actor's death, but added that the cause of death had not yet been established.
However, Thai newspaper The Nation reported that police believe the actor took his own life, and preliminary investigations found that he hanged himself.
Carradine was part of an acting dynasty which included his father, John Carradine, and brothers Bruce, Keith and Robert.
The star was best known for his role as Kwai Chang Caine in the 1970s TV series Kung Fu, which spawned sequels in the '80s and '90s.
The character became one of the most iconic roles in US TV and earned Carradine both Emmy and Golden Globe nominations.
While his film career saw him working with directors including Martin Scorsese and Ingmar Bergman, the cult actor was considered something of a B-movie legend.
In 2003, after years in the straight-to-video market, Carradine found a new audience thanks to his role in the Quentin Tarantino film Kill Bill.
He was most recently seen on the big screen as a Chinese mobster in Crank: High Voltage, opposite British actor Jason Statham.
Carradine was an accomplished composer, musician, musical performer and songwriter. According to his official website, he was also a sculptor and a painter.
He is survived by his wife, Annie Bierman, and three children including actresses Calista and Kansas.
