Oscar winner Jim Broadbent has joined the seventh season of HBO's "Game of Thrones" for what Entertainment Weekly characterizes as a "significant" -- but, of course, secretive -- role.
The veteran English actor and comedian is known for roles in "Moulin Rouge," "Bridget Jones's Diary" and the "Harry Potter" franchise. He won an Academy Award for best supporting actor for his performance in 2001's "Iris."
This is the first major casting announcement for Season 7, and the lack of details has sent the internet into rumor mode. Some believe Broadbent will play a compatriot of Jonathan Pryce's High Sparrow, while others speculate he could portray a Maester.
The series has overtaken author George R. R. Martin's plot in "A Song of Ice And Fire," the sprawling series of fantasy novels on which the hit drama is based, making it difficult for fans to make educated guesses about Broadbent's character.
The story for Season 7 has also been subject to conjecture. Fans are wondering whether Jaime will betray Cersei, if Sansa will align herself with Littlefinger, and what affect Daenerys will have on the happenings in Westeros.
The seven-episode penultimate season will air in summer 2017.
