During post-production for a lot of movies the sound directors need actors to redo certain lines or sound effects to make them sound better.
For Logan, Hugh Jackman needed to record ADR (Automatic Dialog Replacement) in post-production for his grunts and screams whenever Wolverine would go berserk in the film and it's actually kind of funny!
Can't wait for the scene Hugh Jackman recorded the phrase "Hi.." for!
Logan is rated R and in theaters now.
