"We have about 150 actors at the Globe in total, and they start with getting the experience of what it's like to work with the audience," the director adds. "In Shakespeare's time, the play started at 2 pm, which means the performers and audience shared the same light. The performers didn't address a dark auditorium, so the audience members were more like active participants rather than passive spectators. Once the performers get used to that, they can take the relationship with the audience on the road."

After having studied acting at the Bristol Old Vic Theatre School, O'Hea joined Shakespeare's Globe in 2012.

At first, he thought it was a "tourist trap" and he never wanted to go there. But after he saw a play and acted there, he "completely fell in love with it".

"The audience is more important than anyone. You can listen to their heartbeat. When you see young people connect with the plays, when you see the light going on in a young person's eyes, life doesn't get better than that," he says.
