British actor and singer Hannah Waddingham revealed the toll of filming an intense 'Game of Thrones' scene, as reported by People. On the recent episode of 'The Late Show' with Stephen Colbert, the 49-year-old actress shared, "Thrones gave me something I wasn't expecting from it and that is chronic claustrophobia."

Waddingham, who portrayed Septa Unella in the popular HBO series, recounted filming the moment in which Cersei (Lena Headey) poured wine on her character's face and demanded she confess her misdeeds.
