'Game Of Thrones' Actor Charles Dance Aka Tywin Lannister To Star In Syfy's New Miniseries 'Childhood's End'

Charles Dance has landed another starring role on TV.

The 68-year-old British actor, who plays Tywin Lannister on the hit HBO fantasy drama series "Game of Thrones," nabbed one of the lead roles in the upcoming Syfy miniseries "Childhood's End," Entertainment Weekly reported.

Based on the 1953 science fiction novel of the same name by British author Arthur C. Clarke, "Childhood's End" follows the peaceful alien invasion of Earth by a mysterious breed of aliens called Overlords. Their arrival ends all war, helps form a world government, and turns the Earth into a near-utopia, but at the cost of humanity's identity, and eventually the planet itself.

The Primetime Emmy-winning actor will portray Karellen, the ambassador for the Overlords who makes first contact with Earthling Ricky Stormgren.

A source told EW that "Karellen's comforting words and amazing technological gifts quickly win humanity's favor, beginning decades of apparent utopia at the cost of human identity and culture. However, his refusal to reveal his physical appearance and insistence on dealing only through Ricky have some people questioning whether his intentions are truly benevolent."

The six-hour miniseries will be directed by Nick Hurran ("Sherlock") from an adapted screenplay by Matthew Graham (BBC's "Life on Mars").

Akiva Goldsman ("Lone Survivor") and Mike DeLuca ("The Social Network") are executive producing the project, which will premiere on Syfy next year.

Despite his character's terrifying death in "Game of Thrones" Season 4 finale titled "The Children," Dance told MTV UK last month that he is not yet done with the TV adaptation of George R.R. Martin's novel series "A Song of Ice and Fire."

 "I'm not completely missing out on the next series. More than that, I'm not going to say," the "Alien 3" actor teased. "You haven't seen the last of Tywin Lannister, is all I'll say."

Since Tywin is already dead, the character may make appearances in either Tyrion Lannister (Peter Dinklage) or Jaime Lannister's (Nikolaj Coster-Waldau) flashback when the series returns for its fifth season next year, according to The Hollywood Reporter.

There are instances in the novel series when Tyrion keeps hearing some of Tywin's final words before being killed. Jaime, on the other hand, spends some time figuring out how to become a good leader after Tywin's death, and by doing so he imagines what  his father would do when faced with difficult situations.
