The Origins of How to Train Your Dragon

How to Train Your Dragon began as a children’s book series written and illustrated by Cressida Cowell. The original novel was first published in 2003 and has since sold over 8 million copies globally (Little, Brown Books for Young Readers, 2024)^[5]. The series follows the adventures of Hiccup Horrendous Haddock III, a small and unorthodox Viking who must capture and train a dragon to prove himself to his tribe. Cowell’s books are known for their humor, heart, and hand-drawn illustrations, blending fantasy with coming-of-age themes.

DreamWorks Animation adapted the first book into a feature film in 2010, taking significant creative liberties while retaining the core message. The film was a critical and commercial success, earning approximately $495 million at the worldwide box office (Box Office Mojo, 2024)^[6]. The film’s success spawned two sequels: How to Train Your Dragon 2 (2014), which grossed around $621.5 million worldwide (Box Office Mojo, 2024)^[7], and How to Train Your Dragon: The Hidden World (2019), which grossed about $525.7 million (Box Office Mojo, 2024)^[8]. The trilogy earned multiple Academy Award nominations for Best Animated Feature (Academy of Motion Picture Arts and Sciences, 2024)^[9].

In 2025, a live-action remake was released, directed by Dean DeBlois and starring Mason Thames as Hiccup and Nico Parker as Astrid. The film earned approximately $262.9 million in the United States box office (Rotten Tomatoes box office data, 2025)^[10]. The live-action version stays close to the 2010 animated film while adding new depth to the characters and world.

Key Characters and Their Development

How to Train Your Dragon features a rich cast of characters whose growth drives the narrative. Hiccup, the protagonist, begins as an outcast in his Viking tribe, the Hairy Hooligans. He is physically weak and intellectually curious, traits that make him a disappointment to his father, Stoick the Vast. Hiccup’s defining moment comes when he befriends a wounded Night Fury dragon he names Toothless. Instead of killing the dragon, as Viking tradition demands, Hiccup learns to understand and communicate with him. This act of empathy changes everything.

Astrid, Hiccup’s peer and eventual partner, starts as a fierce and competitive warrior who embodies the tribe’s traditional values. As the story progresses, she becomes one of Hiccup’s strongest allies. Actor Nico Parker, who plays Astrid in the 2025 live-action film, described her character’s arc: “Astrid in How to Train Your Dragon represents that moment when you realize your courage has to expand beyond what you were raised to believe – she learns that real strength is being willing to change your mind” (Empire Online, 2025)^[11]. Stoick, voiced by Gerard Butler in both the animated and live-action films, evolves from a stern father into a figure of understanding. Butler noted, “What I love about How to Train Your Dragon is that it’s disguised as this big Viking adventure, but underneath it’s a story about fathers and sons learning to see each other clearly” (Variety, 2025)^[12].

Toothless, the last known Night Fury, is a central figure in the story. Though he does not speak, his expressive animations and bond with Hiccup make him one of the most beloved characters in modern animation. The relationship between Hiccup and Toothless is the emotional core of the franchise.

Core Themes: Empathy, Leadership, and Change

How to Train Your Dragon is fundamentally about empathy and the courage to challenge tradition. Dean DeBlois, the director of the 2010 animated film and the 2025 live-action remake, captured this idea: “At its core, How to Train Your Dragon has always been about empathy – about a boy who chooses to understand the thing everyone around him is taught to fear, and how that choice transforms an entire culture” (The Hollywood Reporter, 2025)^[13]. This theme resonates across all versions of the story, from the books to the films. Hiccup’s decision to see dragons as creatures worthy of respect, rather than as enemies to be defeated, sets him apart from his tribe and ultimately leads to a new era of peace.

Leadership is another key theme. Hiccup becomes a leader not through physical strength but through intelligence, compassion, and the willingness to be different. Mason Thames, who plays Hiccup in the live-action film, explained: “Hiccup’s journey in How to Train Your Dragon is about realizing that leadership isn’t about being the strongest; it’s about being brave enough to be different in front of everyone you care about” (Los Angeles Times, 2025)^[14]. This redefinition of leadership is a powerful message for audiences of all ages.

Cressida Cowell, the original author, also emphasized the importance of using one’s mind and heart: “The whole idea behind How to Train Your Dragon is that the smallest, most unlikely person can change the world, not by fighting harder, but by using their brains, their heart and their imagination” (The Guardian, 2024)^[15]. This message of quiet strength and creative problem-solving is woven throughout the entire franchise.

Cultural and Box Office Impact

How to Train Your Dragon has left a significant mark on popular culture. The animated film trilogy is widely regarded as one of the best in modern animation, praised for its storytelling, character development, and visual artistry. The first film’s 99% critic approval rating on Rotten Tomatoes is a testament to its quality (Rotten Tomatoes, 2025)^[3]. The franchise has also spawned television series, video games, stage shows, and theme park attractions. The books, translated into more than 40 languages, have introduced the story to a global audience (Hachette Children’s Group, 2024)^[4].

The franchise’s box office success is remarkable. The combined global box office revenue for the original animated trilogy exceeded $1.6 billion (Box Office Mojo, 2024)^[1]. With the 2025 live-action film, the total has surpassed $1.9 billion (Universal Pictures investor presentation, 2025)^[2]. The live-action film earned roughly $262.9 million in the U.S. alone (Rotten Tomatoes box office data, 2025)^[10], demonstrating the enduring appeal of the story. The franchise’s themes of empathy and understanding have also made it a favorite among educators and parents, who use it to teach lessons about tolerance and critical thinking.

Practical Tips for Engaging with the Franchise

For newcomers, the best starting point is the 2010 animated film. It sets up the world and characters beautifully and is widely available on streaming platforms. After watching the trilogy, consider reading the books to experience the original story. The books are quick reads and offer a different perspective on Hiccup’s adventures.

For fans who want to explore deeper, the television series Dragons: Riders of Berk and its sequels bridge the gap between the first and second films, providing more character development and dragon lore. The 2025 live-action film is best enjoyed after the animated trilogy, as it assumes familiarity with the story. Finally, consider visiting theme park attractions or playing the video games for an interactive experience.

A great way to stay updated on the franchise is to follow news from reputable sources like Animation Magazine, which covers developments in the world of How to Train Your Dragon and other animated properties.
