Oh Benedict, you're an actor, for pity's sake- heir to Vincent Crummles and his ilk; when exactly did you cease to be a rogue and vagabond?

The coronavirus may kill of a lot of our theatres. Dame Judy was on TV last night saying how awful this would be. Well, yes and no. Jobs will be lost and that's terrible- but theatres are one thing and theatre is another. Theatre- which is a branch of story-telling- is a perennial human need- and will survive the demise of the pompous and expensive buildings we currently think we need. Shakespeare used to put on his shows in inn yards- and the liveliest theatre building I know is his rebuilt Globe- which is simply an inn yard upgraded.
All you need to do theatre is a space of some sort and a bunch of enthusiastic show-offs. You don't even need a text- though it probably helps. You certainly don't need lots of fancy lighting and stage machinery. All that impressive technology just widens the gulf between players and played-to. Keep the stage as bare as you can and get the audience to use their imaginations. The imagined tree will always be more tree-like than a pasteboard one- and the more flats you wheel on the less the scene is going to look like a wood near Athens. As Mickey Rooney said to Judy Garland, looking round the crummy old barn in which they've been rehearsing- "Let's do the show right here!"
