Prince William may be second in line to the British throne behind his father Prince Charles, but he is not in a rush to be king anytime soon.

William is profiled in the new True Royalty TV documentary “Prince William: A Monarch in the Making,” which is set to take a look at the 38-year-old’s journey towards becoming the future king of England.

The documentary was executive produced by Nick Bullen, co-founder and editor-in-chief of True Royalty TV, who has been making programs about the royal family for two decades.

He has also worked closely with Charles for the past eight years.

“We were being told that William was very much stepping up in his role as a more senior member of the royal family in many ways, in terms of his public profile and what he was doing,” Bullen told Fox News.

“The word that was used was ‘his monarchy manifesto,’ which I quite like. It’s… an idea of what sort of king he’s going to be.”

William is so popular in the United Kingdom that some Brits have called on him to bypass his 71 year-old father for the throne.

Bullen, however, said that there is no way this would ever happen.

“You can say it as much as you like, but it’s never going to happen,” he said with a laugh.

“When the queen very sadly dies, Prince Charles will be the king. There is no discussion. That’s what the queen wants. That’s what the Prince of Wales wants. And I know that’s what William wants. And you know, William is in no rush to be the king.”

“Here’s the weird thing that you have with the royals, and I’ve spoken to the Prince of Wales about this — to get the top job, you’re essentially wishing your parent or grandparent to be dead,” Bullen added.

“You know it’s coming, you know this job will come eventually, but you’re in no rush to get that job. For Charles to be king, his mother will have to die. So for William to be king, his father would have to die. Nobody wants that. It’ll happen in due course and William is in no rush for it. So it’s the queen, the Prince of Wales and then William — that’s the order.”

While William isn’t in a rush to be king, the future is very much on his mind.

“He’s a very 21st-century royal [but] he’s clearly learned a lot from his father and he’s been coached by his grandmother,” said Bullen.

“So all that heritage still sits with him. And in the documentary, you’ll see he puts duty first. The crown comes first, but you know, he’s married to a woman who is not the classic royal bride. She’s from a family upbringing that’s much more similar to a lot of ours. And I think that in itself makes him different.”

In the end, Bullen is hoping that the upcoming documentary will help the public get to know William better and to see him in a new life.

“I hope they come out with a new respect for William,” he said. “There is more to this young prince than perhaps we all first realized.”
