When Prince Charles and Princess Diana divorced in 1996 after his affair with Camilla Parker Bowles, the Prince of Wales quickly lost popularity with the British people. However, a new television special suggests the heir to the throne may not be as heartless as people seem to believe.

Following chats with members of the royal family for the upcoming program “Prince Charles at 70,” filmmaker John Bridcut revealed the Prince of Wales’ public persona differs from his behavior behind palace walls.

Birdcut told DailyMailTV that Prince Charles doesn’t mind giving off a stern vibe while in front of cameras. However, the filmmaker suggested Charles probably took the time to advise Meghan Markle and Prince Harry amid the negative press the couple has been receiving.

“I would have thought that his approach would be that you just carry on doing the job. He wouldn’t have added to that. His attitude would be that some of the attacks, he would feel were unfair,” the filmmaker said.

“He would apply himself and just carry on doing the job and soldier on and that’s what he’s done and it's borne fruit.”

Birdcut revealed Charles probably used his own experiences from his first year of marriage to Princess Diana to help the couple move past the public scrutiny.

The filmmaker noted, Charles gave the world a glimpse of his compassionate side at Meghan and Harry’s royal wedding when he walked his son’s bride down the aisle. Despite the sweet moment, Charles isn’t comfortable publicly displaying his softer side.

“He has got a natural aversion to being seen or described in any way that he would see as saccharin,” Birdcut explained.

“He does not want to be seen as a sentimental or touchy-feely, because I think that’s part of what he sees as his private life and his private existence. So he doesn’t push that side of things.”

“Prince Charles at 70” will air Sunday at 8 p.m. EDT on PBS.
