Here, Luke Evans chats with IGN about The Hobbit while playing the new Lego Hobbit video game as his own character — Bard. IGN does make it awful hard by firing questions at him about the films and his character while he’s playing!
He does mention that Bard’s over-riding motivation is his family, then adds:
In the third film it’s not just his kids he has to look after — but I can’t talk about it anymore or I’ll spoil it.
