**King Charles and Prince William Share Heartwarming Moment in New Royal Documentary**

A heartwarming exchange between King Charles and his son, Prince William, has been captured in a new behind-the-scenes documentary set to be released by the BBC.

The upcoming film, titled “Charles III – The Coronation Year,” offers a glimpse into the preparations leading up to the grand coronation ceremony that took place earlier this year.

Throughout the documentary, viewers are given a rare insight into the royal family's nervous anticipation and meticulous planning for the significant event.

One particularly touching moment showcases Prince William and King Charles sharing a light-hearted joke, displaying a genuine bond between father and son.

In a scene from the documentary, Prince William is seen assisting King Charles with his stole royal, a symbolic cloth band representing the sacred nature of kingship.

Playfully, Prince William remarks on the complexity of the garment's catch, humorously questioning whether it will cooperate on the actual day.

King Charles responds in jest, teasing about his own “sausage fingers” in comparison to his son's nimble ones, sparking shared laughter between the pair.

Another endearing moment captured during the rehearsals involves Prince William practicing his pledge of allegiance to his father.

The Prince of Wales playfully suggests planting a kiss on King Charles' cheek, playfully noting his preference for the left side.

These light-hearted interactions offer a glimpse into the more personal side of the royal family dynamics.

Scheduled to premiere on Boxing Day, the 90-minute documentary promises exclusive behind-the-scenes footage and interviews with key figures, including officials, family members, and senior royals.

The film will document pivotal events from King Charles' first year on the throne following the passing of Queen Elizabeth II in September 2022.

Viewers will witness poignant moments of introspection and emotion as King Charles and Queen Camilla oversee the alterations of their regal crowns and ceremonial robes in preparation for the historic occasion.

The documentary captures the monarch's vulnerability and humanity amidst the grandeur of his new role.

In a lighter segment, the Archbishop of Canterbury, Justin Welby, is shown grappling with a memory lapse during a rehearsal, candidly admitting to his forgetfulness akin to that of a spaniel.

King Charles shares a lighthearted chuckle as the Archbishop fumbles over his lines, underscoring the camaraderie and humor present amidst the serious preparations.
