David Carradine

Family and stars alike are sharing fond memories of David Carradine. The actor, 72, was found dead Thursday in his hotel room in Bangkok, where he was reportedly working on a movie.

"I was deeply saddened by the news of David Carradine's passing," director Martin Scorsese told the Associated Press. "We met when we made Boxcar Bertha together, almost 40 years ago. I have very fond memories of our time together on that picture and on Mean Streets, where he agreed to do a brief cameo."

Carradine appeared in more than 100 films, with directors including Scorsese, Ingmar Bergman and Quentin Tarantino, but he was best known for his role as Kwai Chang Caine on the television series Kung Fu, which ran from 1972 to 1975.

He was a member of an acting family that included father John Carradine, brother Bruce Carradine, half-brothers Keith and Robert Carradine and nieces Ever Carradine and Martha Plimpton.

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

Office star Rainn Wilson remembered Carradine on Twitter. "R.I.P. David Carradine," he wrote. "You were a true hero to so many of us children of the '70s. We'll miss you, Kwai Chang Caine."

Carradine was married five times, marrying the fifth, Annie, in 2004. He had two daughters, Calista Miranda and Kansas.
