Celador is a British television and film production company founded in 1983 that is best known for producing the game show "Who Wants To Be A Millionaire?". It was originally independent but was later acquired by other companies before management completed a buyout. Celador earns money through various means of financing including initial capitalization, project capitalization, and co-funding partnerships with other small companies. Some of Celador's notable film productions include Dirty Pretty Things, The Descent, and Slumdog Millionaire. Though successful, Celador is considered relatively small compared to larger competitors in the film industry like Sony Pictures Entertainment and Film4 who have greater financial resources.
