Colin Firth Was Replaced By Ben Whishaw In Paddington
The wonderful talking bear Paddington was originally supposed to be voiced by Colin Firth, but somewhere down the line (after the actor recorded most of the lines), the realization set in that the actor's voice didn't match the animation of the cute bear. “It’s been bittersweet to see this delightful creature take shape and come to the sad realization that he simply doesn’t have my voice.” Firth was replaced by Ben Whishaw.
"Certain scenes within this movie feature James Purefoy as V, who was originally cast in the role, but replaced by Hugo Weaving four weeks into filming. Weaving's voice was simply dubbed over Purefoy's performance in post-production. Director James McTeigue said in an interview: " 'Can I tell the difference? Yeah. Can the audience tell? I doubt it.' "
