She might play Queen Elizabeth on the upcoming season of “The Queen”, but even Olvia Colman had nerves when she met the real Queen.

“I have accidentally met the Queen,” Colman told Entertainment Weekly.

“It was at a British Film Institute gathering to raise the profile of British film, independent film,” the actress continued. “We suddenly found ourselves, two hundred people, in a big queue. I thought maybe we were going in to have some food. I hadn’t read the order of the day. [I] looked around the corner, and there was the Queen and Prince Philip.”

That is when the panic set in.

“[I] went, ‘Oh! Oh no! I don’t know what to do!’ And a gentleman with epaulettes said, ‘Don’t overdo it, little bow, and you say, Your Majesty, and your Royal Highness, and go. Make it as swift as possible and go.’ ‘Alright, Okay.’ And I managed to remember what to say, sort of sticky-handed and bit sort of stumbly. That was it!”

Although the one thing that might be more nerve-racking is taking over the role from Clarie Foy.

“It’s horrendous,” she teased. “Everyone loves Claire, so I have got the worst job in the world at the moment.”

“It’s the same as any classical play you do — everyone will have already played that part before,” she added while pointing out all famous faces have been portrayed multiple times.

“[Although] the first week, I did feel myself trying to do Claire impressions. ‘What would she have done?'”

Season three of “The Crown” hits Netflix on Nov. 3.
