Celador is an independent entertainment company founded in 1983 that produces television shows, films, radio stations, and theater shows. As a smaller company, Celador works on projects individually and co-funds films with other companies. Some of Celador's most well-known productions include the TV game show "Who Wants to Be a Millionaire," films like "Slumdog Millionaire" and "The Descent," and they own 18 UK radio stations. While Celador produces smaller, lower-budget projects than larger competitors like Sony Pictures, they are comparable in size and production style to independent film companies such as DNA Films.
