Larry Hagman of "Dallas" diagnosed with cancer

NEW YORK - Larry Hagman has been diagnosed with cancer.

The 80-year-old actor is famous for playing J.R. Ewing on "Dallas." In a statement Friday, he said: "As J.R. I could get away with anything — bribery, blackmail and adultery. But I got caught by cancer."

Hagman declined to specify what kind of cancer he's contracted, but said it's "a very common and treatable form." He plans to continue working on a new reboot of "Dallas" for TNT, which begins production Monday.

The new "Dallas" focuses on the Ewing offspring as they clash over the future of the family dynasty. The original prime-time soap opera aired on CBS from 1978 to 1991. Hagman underwent a liver transplant in the mid-1990s.

Said Hagman: "As we all know, you can't keep J.R. down!"
