How to Train Your Dragon (2025) Behind The Scenes | Making of | VFX & CGI Magic

Back in 2010, DreamWorks released How to Train Your Dragon, an animated masterpiece that captured hearts with its breathtaking flight sequences and the unforgettable bond between Hiccup and Toothless. And now, in 2025, the beloved story has soared into a brand new live-action adaptation. But here's the real magic. How do you take a fantastical world filled with dragons and vikings and make it real on the big screen? The answer lies in a seamless mix of practical sets, advanced CGI, and groundbreaking visual effects. From rideable dragon puppets to stunning real world landscapes, the filmmakers pulled out all the stops. So, just like always, let's pull back the curtain and discover how much work went into bringing this fantasy world to life. One of the most iconic visuals in How to Train Your Dragon is Hiccup soaring through the skies on Toothless. In the live-action version, the filmmakers knew this had to feel authentic, not just a CGI illusion. To create this, the team built rideable dragon puppets. Yes, actors physically climbed onto large rigs designed to look and move like Toothless. These weren't just stationary props. The puppets had limited motion functions like head turns, eye-line cues, and even subtle breathing movements. They gave the actors a real physical presence to interact with. The puppetry was led by Tom Wilton, best known for his groundbreaking work on War Horse. He ensured that every flick of Toothless' head or blink of the eye gave the actors something tangible to react to, grounding the fantasy in physical reality. The heart of the flying sequences came from multi-axis gimbals, giant mechanical rigs that could tilt, spin, and simulate the turbulence of flight. Framestore's VFX and engineering team programmed eight-axis gimbals so each dragon had its own unique flight cycle. When Hiccup banked left or Toothless shot upward, those motions weren't faked in post. They were felt in real time on set. And of course, to sell the illusion of speed, industrial wind machines blasted the actors with powerful gusts, nicknamed by the crew as the Beyonce fans. Actors later admitted it felt like riding a mechanical bull in the sky. Uncomfortable, exhausting, but breathtakingly real once the CGI dragons were layered in. Of course, Hiccup isn't the only viking with a dragon. Astrid, Snotlout, Fishlegs, and the twins all have their loyal companions, and each requires the same level of realism. For these sequences, filmmakers built smaller dragon rigs mounted on motion bases and multi-axis gimbals. Each puppet gave the actors a tactile seat, reins, and eye lines so their performances matched the emotional beats of the moment. Later, Framestore's VFX artists replaced these rigs with fully CGI dragons, extending wings, scales, and tails, while keeping the natural timing and genuine reactions from the live-action performances. Director Dean Desbois emphasized this hybrid approach. Practical rigs for authentic acting, CGI for spectacle. Without the puppets, actors might have looked disconnected, riding just thin air. With them, every glance, grip, and scream felt grounded. It's not just the dragons that needed to feel real. The landscapes themselves had to breathe with authenticity. To design Burke and the surrounding skies, the production team embarked on an aerial location shoot across the Faroe Islands. Using helicopters, they filmed sweeping shots of rugged coastlines, dramatic cliffs, and ocean passages. These weren't meant to appear directly in the movie, but served as creative reference footage for the VFX team. By studying how light scattered across the cliffs, how the ocean mist rose, and how shadows shifted with altitude, animators could create more immersive flight sequences. Burke's geography, its Viking village, towering cliffs, and hidden sea caves was digitally extended, but rooted in these real-world aerial studies. As the director explained, you can animate fantasy, but you need reality as your anchor. Let's talk about this most striking scene when Stoick the leads a massive Viking fleet across the sea towards the dragon's home. On screen, it looks like an enormous armada sailing through open waters, but in reality, the entire sequence was built inside a studio. The production team constructed a large boat set, which remained stationary. To give the illusion of movement, the boat was placed on mechanical stands that provided subtle rocking motions while background obstacles were shifted behind the set to simulate forward motion. This way, it appeared as though Stoick's ship was cutting through the waves. Of course, the real magic came in post-production. Using CGI, the filmmakers digitally placed the ship into a vast ocean environment and extended the fleet by adding countless additional army boats of Stoick. What began as a single constructed set became, on screen, a sprawling Viking army stretching across the horizon, delivering the epic skill the scene demanded. One of the most exciting parts of the film shows Hiccup, Astrid, Fishlegs, and their friends undergoing dragon training, learning firsthand how to face and understand these creatures. It's a thrilling sequence that captures the essence of the Viking teens' journey. To bring this to life, the filmmakers built a detailed practical set inside a studio surrounded by large blue screens for later digital extensions. Real practical effects, such as controlled bursts of fire, were used on set to simulate dragon breath, giving the actors something tangible to react to. Later, CGI dragons were seamlessly integrated into these shots, transforming the practical training ground into a larger, more immersive dragon arena on screen. Perhaps the most emotional and iconic scene in the film is when Hiccup reaches out and touches Toothless' face for the very first time, a moment that marks the beginning of their extraordinary friendship. On set, Toothless wasn't a full dragon, but a specially designed puppet head built for interaction. This allowed the actor playing Hiccup to physically connect with something real, capturing the intimacy and vulnerability of the moment. Crew members operated the puppet just off camera, ensuring Toothless' subtle movements, like breathing or tilting his head, looked natural. The sequence was filmed entirely in a studio-built practical environment, with a blue screen backdrop surrounding the set. This made it possible to extend the environment digitally, turning the controlled studio stage into a lush, forested setting that immerses the audience in Hiccup's world. Also, other emotional interactions and scenes between Hiccup and Toothless were also filmed in this way, using partial puppets and practical props on set, combined with VFX and post-production to fully realize the dragon's expressions and body language.
