The Harry Potter alum has been cast in a mysterious but "significant" role, according to Entertainment Weekly. HBO and the Game of Thrones producing team didn't give out any further details in order to prevent major storylines from hitting the web.
Previously, recent casting notices for the HBO epic were leaked, and while Broadbent fits the description asking for a "venerable priest" in his 60s with a "characterful face," TVGuide.com has a different theory (and posted cast listings have been misleading before). We think Broadbent would fit in really well at the Citadel with Sam (John Bradley) — possibly even as the head maester.
Broadbent won an Academy Award for his supporting role in the 2001 film Iris, and his storied career includes appearances in Cloud Atlas, Longford, Brazil, Indiana Jones and the Kingdom of the Crystal Skull, Doctor Who and much more.
Who do you think Broadbent could play?
