'Dallas' hit a chord back in the late Seventies and Eighties because it was the age of greed: here you have this unapologetic character who is mean and nasty and ruthless and does it all with an evil grin. I think people related to JR back then because we all have someone we know exactly like him. Everyone in the world knows a JR.

The appearance marked the first time the two performers had acted together since Eden appeared with Hagman in a five-episode arc on Dallas in 1990. Ultimately the person who pulled the trigger was revealed to be Kristin Shepard (played by Mary Crosby) in the "Who Done It?" episode which aired on November 21 1980. He also directed (and appeared briefly in) a low-budget comedy and horror film in 1972 called Beware! The Blob also called Son of Blob a sequel to the classic 1958 horror film The Blob.

Hagman had supporting roles in numerous films including Fail-Safe Nixon and Primary Colors. His television appearances also included guest roles on dozens of shows spanning from the late 1950s up until his death and a reprisal of his signature role on the 2012 revival of Dallas. Hagman was the son of actress Mary Martin.
