Gerard Butler, Mason Thames and Nico Parker chat with ET's Cassie DiLaura inside Universal Orlando Resort's new Epic Universe park, which features an immersive version of the Isle of Berk, the setting for their live-action remake of 'How to Train Your Dragon.' Gerard reprises his role of Stoick the Vast from the animated films, while Mason takes on the role of Hiccup Horrendous Haddock III and Nico, the part of Astrid Hofferson. The trio share what it was like acting alongside a puppet as the dragon Toothless and how they bonded on set as a family. 'How to Train Your Dragon' soars into theaters on June 13.
