When does French and Saunders return?

French and Saunders is a British sketch comedy television series written by and starring comedy duo Dawn French and Jennifer Saunders. It is also the name by which the performers are known when they appear elsewhere as a double act. The show was given one of the highest budgets in BBC history to create detailed spoofs and satires of popular culture, movies, celebrities, and art. In a 2005 poll to find The Comedian's Comedian, the duo were voted among the top 50 comedy acts ever.
