Can you do anything to overcome nerves?
"I do something called EFT, which is emotional freedom technique, otherwise known as tapping, which really helps me."

"Yes, so I’ll do that before a first day of filming. And if there’s a particularly tricky scene I’m worried about, I’ll do it before then as well."
