Bradley Cooper | Christopher Walken & Owen Wilson

Two-time Grammy Award winner Bradley Cooper has received his fair share of accolades and nominations, which only goes to show that the actor and filmmaker has proved he has a certain level of standards when making movies. He has also been listed among the most influential people in the world back in 2015, proving that his fame is not only confined to North America.

Perhaps because Christopher Walken has such a distinctive speech style that everyone can impersonate him with ease, but no one could channel him better than Cooper could. The actor was so carried away in the imitation that he ended up speaking more as Walken, with the voice pitch, than as himself. Cooper also did Owen Wilson with the distinctive voice pattern. He certainly could do an impression of other celebrities, and he is not too shy to show these skills during interviews.
