You'll find a plethora of theaters in Barcelona, but productions will logically be in Spanish or Catalan. If you want to give your listening comprehension skills a workout, head to the Palau de la Virreina arts information office for listings and pamphlets.
Or ask for the "Guía del Ocio," a comprehensive weekly guide to cultural events, at any kiosk.
