Celador is a British production company formed in 1983 that is best known for producing the game show Who Wants to Be a Millionaire. While Celador is a small company, it has been successful in releasing seven films over ten years. However, it faces competition from much larger studios like Sony Pictures and production companies like Film4. To fund its film The Descent, Celador had to co-fund the project and sell the distribution rights to Pathe upfront to raise enough money for production.
