Matt Smith shared that Prince Harry had a surprising nickname for him after he starred as Prince Philip in The Crown.
Smith played the late Duke of Edinburgh in the first two seasons of the popular Netflix show.
He later met Prince Harry at a polo match in 2017, and the Duke of Sussex had a surprising nickname for the actor.
Speaking about the duke, Smith told the BBC: "He was like 'Alright grandad?' I was like 'Alright mate?'"

The actor also claimed that Harry used to watch The Crown.
Smith said: "I can’t claim to know if he watches [The Crown] currently, but he watched a bit of it then.
"I heard the Queen had watched it, and she used to watch it on a projector on Sunday night, apparently."
However, Prince Philip did not enjoy The Crown, according to the actor.

He continued telling TODAY: "A friend of mine sat next to [Philip] at a dinner once… and my friend couldn’t resist by the end of the meal.
"He was like, 'Philip, I have to ask, have you watched The Crown?'
"And apparently [Philip] turned around to him and said, 'Don’t be ridiculous.'"
Smith was nominated for an Emmy due to his portrayal of Prince Philip.
