CPL Productions (formerly Celador) is a British entertainment company originally formed in the United Kingdom in 1981 as an independent television production company. It created and produced a number of popular light entertainment shows and is best known for the TV format Who Wants to Be a Millionaire? and the film Slumdog Millionaire which, in 2009, collected seven BAFTAs, four Golden Globes and eight Oscars including Best Director and Best Picture. The name Celador is a re-spelling of "cellar door", a phrase whose sound is often noted to be particularly euphonious.
