Walking Out Of Performances at interval.

I have been in theatre for more than 18 years and the last 5 I have been working in London's west end and regional theatres. Walking out of Productions is as common as walking in. I have seen some total rubbish. I don't ever sit there and say I could do better. That in my opinion is arrogant even if you know you could. I very rarely go to the theatre to see a particular actor. So, in respect I am not walking out on the actors, but the overall production. If you order a meal from a restuarant and you don't like it, you leave if or change it, you don't eat it just to please the chef. It isn't just the chef that created the meal, but everybody from the waiter to the kitchen staff. It is the same in the theatre. I saw ' Prisoner on second ave ' with Dreyfuss at the ' H/market(lon) it was great, but sadly let down by lights, sound, slow set changes etc. I left at interval. Later on in the run I had read in the 'stage' that all of the technical factors of the producting had been rectified, so I went along and enjoyed a fantasic experience. Theatre should be an experience. Don't sit through something just to please. Theatre is about the extraordinary not the ordinary.
