The London visit of France's Théâtre National Populaire is the first of several international seasons at The National Theatre. It brings two of the most brilliant European directors to London: Patrice Chéreau, who directed this year's 'Ring Cycle' at Bayreuth, and Roger Planchon. Arena went to Lyons where the Théâtre National Populaire, one of France's leading theatres, has found a permanent home to film Chéreau's original and much discussed 'La Dispute' by Marivaux and Planchon's highly acclaimed 'Tartuffe'.
