Stephen Colbert is preparing for a star-studded afterparty to celebrate the conclusion of 'The Late Show with Stephen Colbert,' which is ending its 11-year run on CBS. The final taping will take place at the Ed Sullivan Theater in New York City, followed by a festive gathering featuring a red, white, and blue theme and a dress code of 'Fired & Festive.' The last episode will air on Thursday at 11:35 p.m. and will include special guests such as Jon Stewart, Steven Spielberg, David Byrne, and Bruce Springsteen. In a twist, Colbert will take on the role of the interviewee in his popular segment 'Colbert Questionert.' Other late-night shows, including 'The Tonight Show' and 'Jimmy Kimmel Live!', will refrain from airing new episodes as a mark of respect for Colbert's farewell. Following the show's conclusion, CBS will replace its timeslot with 'Comics Unleashed' and 'Funny You Should Ask.' Colbert's departure comes after CBS announced the show's cancellation due to financial reasons, despite its strong performance. Colbert has expressed his frustration over the cancellation, indicating that he will continue to speak candidly about political issues in the future. He has also hinted at a new project involving a film adaptation of 'The Lord of the Rings.'
