JR Ewing will get a send-off with a proper funeral on Dallas.
The second season of the Dallas revival will air in the US next month.
American TV network TNT announced on Tuesday that it will hold a funeral for Hagman's memorable character at some point in the 15-episode season but that it hasn't been filmed or scheduled yet.
Hagman died in late November at the age of 81.
He had kept working on Dallas until soon before his death and will appear in several of the new season's episodes.
However TNT spokeswoman Erin Felentzer says the network isn't saying how Hagman's iconic character will be killed off.
