Before his death on Friday from complications from throat cancer, Larry Hagman, who plays the devious oil tycoon, had filmed six of 15 episodes for season 2 of Dallas.
Now, the show's writers and producers will have to find a way to finish filming the season without the show's most iconic character.
According to EW.com, producers want to give J.R. "the proper sendoff that he deserves."
"Larry Hagman was a giant, a larger-than-life personality whose iconic performance as J.R. Ewing will endure as one of the most indelible in entertainment history," executive producers Cynthia Cidre and Michael M. Robin said in a statement on Friday.
In the show's first season, an aging – but still scheming – J.R. spent some time in a nursing home to be treated for depression.
TNT, which airs Dallas, said in a statement: "We will be forever thankful that a whole new generation of people got to know and appreciate Larry through his performance as J.R. Ewing."
Deadline.com reports that it's currently unclear how Hagman's death will affect the show but speculates there may be a hiatus in filming, so "the writers can rework the scripts for the remaining episodes" without him.
Like the 1980 cliffhanger on the original Dallas – which left viewers asking, "Who shot J.R.?" – a farewell episode will likely be must-watch TV for fans.
