Although TV is exhausting, the longest performance you do there is about two minutes, and that's your whole performance, then you have a break and then you do another two minutes. Sustaining something for two hours, as you must in theatre - that's when it becomes an art form, this is when you become someone like a ballet dancer or a pianist or painter, where a lifelong training and experience is brought to the fore. So if I'm not going to dishonour and disenfranchise 45 years of work, I need to come back to the theatre whenever I can.
