Dean DeBlois, the creative mind behind both the original animated and the upcoming 2025 live-action adaptation of How to Train Your Dragon, has shared insights on why David Tennant, who voiced the character Spitelout in the animated series, was not asked to return for the same role in the live-action film. Spitelout is depicted as a robust, warrior Viking from the Hairy Hooligan Tribe, and although Tennant voiced him previously, the role in the live-action version has been given to Peter Serafinowicz.
In a discussion with The Hollywood Reporter, DeBlois was queried about considering other original voice actors for the live-action remake, besides Gerard Butler. The director praised Tennant’s skills but expressed regret over not having a “sufficiently substantial role” to offer him. He elaborated that Tennant was not suitable for the physical demands of Spitelout’s character in the live-action format, but he remains hopeful about casting Tennant in a future “ideal” role. Below is his statement:
David Tennant is an incredibly gifted actor, and it was unfortunate that we didn’t have a substantial enough role for him in the animated series. The character of Spitelout, who is Snotlout’s father, requires a physically imposing presence that didn’t align with David’s physique. Perhaps in the future, we can cast him in a role that’s a perfect fit. Regarding Gerard, he was initially unavailable due to other commitments, but the 2023 actors’ strike shuffled his schedule, creating an opportunity for us to include him in the cast.
What the Changes Mean for the How To Train Your Dragon Remake
Dean DeBlois Aimed to Reunite the Original 2010 Film Team
Gerard Butler is among the few original cast members reprising his role in the 2025 live-action remake of DreamWorks’ How to Train Your Dragon, which was nearly impossible due to his packed schedule. Efforts from both parties made his return feasible, and DeBlois emphasized that without the “unexpected window,” another actor might have been cast as Stoick in the new movie.
The nostalgia of the 2025 How to Train Your Dragon transcends its cast. John Powell, the composer from the animated film, also returned. DeBlois mentioned that Powell was the first person he contacted, aiming to “embrace the original audience while welcoming a new generation.” It appears DeBlois has made significant efforts to bring back the original essence of the 2010 movie for the remake.
With a sequel to How to Train Your Dragon announced, there has been speculation about who will play Hiccup’s mother, Valka, originally voiced by Cate Blanchett. DeBlois has expressed his desire for Blanchett to return for the live-action adaptation, which would make her the second original cast member to do so if she accepts.
Reflections on the 2025 How To Train Your Dragon and Its Future
The Potential Return of David Tennant to How To Train Your Dragon
While Tennant was perfect for voicing Spitelout, his physical mismatch for the live-action portrayal makes a direct transfer impractical, potentially detracting from the film’s authenticity. However, Tennant could still make a delightful cameo appreciated by longtime fans.
Future opportunities might arise for Tennant in a How to Train Your Dragon sequel, depending on his interest and availability amidst his busy schedule, which includes projects like Rivals season 2 and Good Omens. With the sequel planned for a June 2027 release, there’s a chance Tennant could still be involved if the timing aligns.
