A Number
Old Vic

CLONING has often been thought a subject best left for sci-fi, but at the turn of the 21st century — when Caryl Churchill’s play A Number was first staged — the prospect of humans being cloned was raised after a Finnish-Dorset sheep named Dolly became the first mammal to be cloned from an adult cell.

Now 20 years later, and the politics of our DNA has taken centre stage again with companies like 23andMe offering a full breakdown of your genetic makeup from a saliva sample. As if Silicon Valley doesn’t have enough of our data.

But if A Number is on one level a warning sign about the drawbacks of human cloning, it is many other things beside. It’s also a timeless analysis of nature vs nurture, and the complex relationship between a father and son.
