In a 2012 interview, Kercheval said of his character’s rival: “J.R. was coming after my ass all the time, so I always had to defend myself.
“If I did something that wasn’t quite right, it’s because I had to.”
After studying music and drama at university, the actor went on to work with Dustin Hoffman in an Off-Broadway production of Dead End, before later heading to Broadway in 1961 in The Young Abe Lincoln.
He then moved from the stage to TV with roles in Search For Tomorrow and The Secret Storm, but his big break came when he was cast in Dallas in 1978.
After the show ended in 1991, he returned for 1996 Dallas reunion, J. R. Returns, and for for a 2004 reunion special.
He later reprised his role once again in the 2012 Dallas reboot which ran until 2014
In addition to Dallas, he also appeared shows such as Kojak,Starsky & Hutch, L.A. Law, Diagnosis: Murder and ER.
He battled a long-running smoking habit over the years, admitting he would often smoke two or three packs a day.
Kercheval was diagnosed cancer in 1994 and had part of his lung removed.
As well as being a heavy smoker, he called himself a “practicing alcoholic” for 20 years before he eventually gave up booze.
He was married four times, and divorced his last wife, Cheryl Paris, in 2004.
The actor had five children from his marriages and had more than six granchildren.
