Celador is an entertainment company originally founded in 1983 that produces films, television shows, radio stations, and theater productions. It started as an independent film studio and produced successful shows like Who Wants to Be a Millionaire? and films like Dirty Pretty Things and Slumdog Millionaire. Though now smaller, Celador funds new projects through investments, co-productions, and profits from past successes. As an independent studio, Celador faces competition from larger studios like Sony Pictures but continues producing films on smaller budgets.
