Royal fans are furious over how animator Gary Janetti has drawn Prince George in Janetti's upcoming cartoon series The Prince.

The Prince, an eight-part series, features a range of royal family members, including Meghan Markle and the Queen, while keeping Prince George as the main character.

Janetti was formerly a writer on Family Guy and Will & Grace and shared a glimpse of Prince George on his Instagram page, with him and his siblings Princess Charlotte and Prince Louis arguing over their Halloween costumes.

The series has attracted big names to voice the characters, including Orlando Bloom as Prince Harry and Sophie Turner voicing Princess Charlotte.

However, a petition to cancel the show is now circling and has garnered around 700 out of 1,000 signatures.

It was created by the Mountbatten-Windsors Royal Fan Page and argues that the series mocks Prince George and exploits an innocent child.

“I would like to put an end to a series that mocks an innocent child, his siblings and his family in order to create comedy,” the petition reads.

“It is very uncomfortable to use a non-consenting child's likeness in this way without considering how it might affect him in the future. It is irresponsible and cruel.

“He is only 7. His siblings are only 5 and 2 and having adults voice them and portray them in ways that are dishonest and crude is very disgusting.”

A Disney producer also believes that the show is "cruel and unfair".

“It’s one thing for film-makers to play fast and loose with the truth in shows like The Crown but poking fun at a seven-year-old child seems cruel and unfair,” the insider was quoted.

"Some things should be off-limits. It’s morally wrong to use a child to get cheap laughs."

Janetti has stated that the jokes are meant "with affection", but the Buckingham Palace has not responded to the controversy so far.
