Kids go through phases, even when they’re royal. Prince William revealed that Prince George has a new favorite film.

During his trip to Northern Ireland with wife Kate Middleton last month, the Duke of Cambridge told a young boy named Reagan that Prince George is now a big fan of “How To Train Your Dragon,” according to Express.

“How To Train Your Dragon” is a 2010 computer-animated film which follows a Viking boy named Hiccup (voiced by Jay Baruchel) who is supposed to be training to kill dragons. Instead, he befriends a beast named Toothless and learns to tame dragons. The DreamWorks Animation film was a big hit, earning nearly $500 million at the global box office. Two sequels have been released since then.

Though DreamWorks is an American studio, the movie is based on a book by British author Cressida Cowell.

In 2017, William declared that “The Lion King” was on repeat at their home. The Disney movie is also an animated flick that was based on the work of a British author. The movie is a take on William Shakespeare’s “Hamlet,” and it was released in theaters when the Duke was just 12 years old.

William, of course, has to keep up with more than just the animated hits. The Duke is also the President of the British Academy of Film and Television Arts. That’s why he was at the BAFTA Film Awards, where he was overheard telling “The Favourite” star Olivia Coleman that he loved her TV show “Broadchurch.”
