Celador Entertainment is an independent British production company formed in 1983 that produces light entertainment and television shows. It experienced early success with shows like Who Wants to Be a Millionaire but was later bought by another company before regaining independence. Celador operates with a small production model relying on partnerships and co-productions for funding and distribution. Some of its most well-known and successful productions include Slumdog Millionaire, The Descent, and various shows by Jasper Carrott. While smaller than major studio competitors, Celador has achieved box office returns that exceed its budgets more so than some larger production companies on films like The Descent.
