We all know that Gary Oldman can be quite the chameleon. From the mustached police commissioner in Christopher Nolan's Dark Knight trilogy, the scarred pimp in True Romance, to being completely unrecognizable in Hannibal, Oldman has no issue disappearing into a role. While we probably most often associate Oldman's transformations with his physical appearance, his voice may actually be the unsung hero. Listening to Oldman's various accents and voices, it is almost hard to believe that they are all coming from the same person. Over his career, he has flawlessly pulled off dialects ranging from American Southern to Russian, and even Transylvanian to whatever he was doing in The Fifth Element. Here is a look at some of Oldman's most impressive and unique voices and dialects.
