Celador Films was founded in 1983 by Jasper Carrott and Paul Smith as an independent production company, though it has since been acquired by other owners. It operates as a small company that produces films through partnerships and freelance workers. Notable films produced by Celador include Slumdog Millionaire, The Descent, and Dirty Pretty Things. While Celador has found success with some films, it faces significant competition from larger studios like Sony Pictures that have substantially higher budgets for film production and marketing.
