Gerard Butler

Gerard Butler is a Scottish actor who provided the voice of Stoick the Vast. He achieved widespread fame for playing the lead role of King Leonidas in the film 300.

Biography
In his review of the film, Roger Ebert joked that Butler seemed to be "channeling" his character of Leonidas when voicing Stoick. He also dryly noted how many of the Scandinavian Vikings in the film spoke with Scottish brogues, including Butler and Craig Ferguson (Gobber).
