They say, "imitation is the highest form of flattery." And as with anything that they say, there's always others who say different. Some say, "imitation is the highest form of piracy." I guess it all just depends on the intention of the imitator.
There is nothing better than seeing an artist nail an impression dead on. Every once in a while there comes along talented people who truly studies the craft and are able to scare you with how good they are. Actor Ross Marquand is just the person to do that. Watch this magnificent freak take on the voices and mannerisms of Brad Pitt, Kevin Spacey, Matthew McConaughey, James Gandolfini, Harrison Ford and Al Pacino.
Personally, I'm not sure which one I liked the best. His Kevin Spacey drops my jaw. Check out Marquand's IMDB page here.
