The cast and crew of hit drama series Dallas are to pay tribute to the show's late star Larry Hagman in a series of extra features on an upcoming Dvd.

Veteran stars of the revamped sex-and-scandal show, including Patrick Duffy and Linda Gray, joined new actors Josh Henderson and Jesse Metcalfe to share their memories of Hagman, who died a year ago this week (beg18Nov13).

The resulting film, titled Memories of Larry Hagman: A Cast and Crew Tribute, will feature on a special four-disc release of the show's 2013 season.

Other extras in the set include a film exploring how Hagman's death - and that of his infamous Dallas character, the backstabbing oil baron J.R. Ewing - was dealt with onscreen, an extended version of the episode showing J.R.'s funeral, and one of Hagman's last ever interviews.

Hagman died on 23 November last year (12) after a battle with cancer.

The Dvd is due for release in February (14).
