Larry Hagman, who created one of American television’s most supreme villains in the conniving, amoral oilman J.R. Ewing of Dallas, has died.

The 80-year-old actor, who starred as JR in long-running US series <i>Dallas</i>, will go ahead with filming TNT’s revival of the soap.

Cult 1980s television series <i>Dallas</i> is to return to the small screen, with 79-year-old US actor Larry Hagman joining fellow veterans.
