'Game Of Thrones' Purple Wedding Spoilers: New Behind The Scenes Feature And Joffrey's Best Moments [VIDEO]

Warning: Full "Game of Thrones" season 4 spoilers.

Fans are still reeling from the latest shocking "Game of Thrones" death. In "The Lion and the Rose," Joffrey was killed at the Purple Wedding and it was quite the challenge to direct such an elaborate event. HBO has released several new "Game of Thrones" season 4 features that explore the creation of the Purple Wedding as well as a look back at Joffrey's best moments.

The "'Game of Thrones' Season 4: Anatomy of the Scene - The Royal Wedding" feature explores the unique nature of the Purple Wedding. According to executive producer and co-creator D.B. Weiss, there will never be another "Game of Thrones" scene that features so many of the main characters in one place. Co-creator David Benioff said they had just four days to shoot the Purple Wedding, a 24-minute scene that would take two weeks to shoot if it was a film production. The costumes, including Margaery's wedding dress, and the Great Sept of Baelor were made to look as regal as possible, notes director Alex Graves.

Graves spent months working on the Purple Wedding and the feast, coordinating such a large set that included dozens of extras and action in the foreground and background. Jack Gleeson, the actor that plays Joffrey, discusses his role as the cruel young king and it is interesting to see the juxtaposition between person and character as Gleeson talks about Joffrey and the Purple Wedding. Gleeson's interview with Entertainment Weekly is an illuminating one as the actor explains why he is retiring from acting at the age of 21 and his reaction to Joffrey's death.

A discussion about the Purple Wedding would not be complete without "A Song of Ice and Fire" creator George R.R. Martin. The author explains the motivation behind Cersei accusing Tyrion of killing Joffrey and the many examples where the siblings threatened each other and what her accusal means for the rest of "Game of Thrones" season 4.

The final "Game of Thrones" behind-the-scenes feature examines the difficult position Jaime Lannister is in now that he has lost his right hand. Without his sword hand, Jaime has lost his identity and now has to learn how to fight left-handed.

What better way to celebrate Joffrey's death than a proper video tribute of the king's best moments? Rather than portraying Joffrey for what he actually is, the tribute has clips of characters giving false praise to the dead king.

The next "Game of Thrones" season 4 episode, "Breaker of Chains," which will focus on the aftermath of the Purple Wedding and Joffrey's death, airs on Sunday at 9 p.m. EDT.
