Larry Hagman, who played J.R. Ewing, hosts the show that includes appearances of older cast members: Linda Gray (Sue Ellen), Victoria Principal (Pam), Patrick Duffy (Bobby), Lucy (Charlene Tilton), Ken Kercheval (Cliff) and Steve Kanaly (Ray), the New York Post reported.
The two-hour show includes outtakes, bloopers and Larry Hagman's personal home movies made during the series.
The cast talks about and view clips of the show, including the famous Nov. 21, 1980, "Who Shot J.R.?" episode and eventually the cast ends up onstage answering questions at The Oil Baron's Ball.
Cast members told some interesting stories, such as every cast member had to shoot the scene shooting J.R., so none of them or the crew knew until the show aired, who really did shoot J.R.
