Actress Hannah Waddingham discussed on 'The Late Show with Stephen Colbert' the mental trauma she endured from filming a 'Game of Thrones' torture scene.

Waddingham was waterboarded for 10 hours, resulting in chronic claustrophobia and physical strap marks.

She joins other 'Game of Thrones' actors in criticizing the show's treatment of its cast, pointing to a culture lacking in support and sensitivity.

The conversation underscores the contrast between the show's practices and current industry standards that include the presence of intimacy coordinators.

Despite the controversy, the 'Game of Thrones' franchise expansion continues with projects like 'House of the Dragon' and 'Dunk and Egg', while some other spin-offs have been cancelled after considerable investment.
