Hagman, 81, who passed away from ongoing complications in his battle with throat cancer on November 21, will be honoured with a public service at the US soap's Southfork Ranch on December 2, which was home to his villainous alter-ego J R Ewing and his family, reported the Huffington Post.
"It sounds like it will happen and I wouldn't be surprised if it does. Larry had such a great sense of humour, he would have loved it," Gene Yusem, Hagman's close friend, said. Fans of the actor who secure a spot at the public memorial will also be able to go on a tour of the ranch ahead of the service.
Hagman's manager John Catalonia revealed the actor will be honoured with two further private services in Texas and California next week. "There will not be an official burial site for Mr Hagman," Catalonia said.
While the 'I Dream of Jeannie' star's ashes were expected to be scattered on the set of 'Dallas' and at various locations around the world, his son Preston says such an announcement is "premature".
