While you might not necessarily be extremely familiar with these guys and their work, their histories are pretty impressive. Clancy Brown is an actor who principally focuses on voiceover, well-known for his parts in Shawshank Redemption, Highlander where he was Kurgan, Starship Troopers, and of course as Mr. Krabs in Spongebob Squarepants! His most recent film, Homefront, is in cinemas now.
Daniel Wu is very well-known indeed in Chinese-language film, principally as an actor, but also a director and producer. He's been in over 40 films and won various awards, including a Hong Kong Film award for directing work in The Heavenly Kings. He most recently appeared in The Europa Report this year.
