Márcio Seixas (1945-) is an (awesome) Brazilian voice actor.
He is known for playing awesome characters in awesome movies, cartoons and series.
Some of his cartoon roles includes Batman/ Bruce Wayne in Batman the Animated Series, Justice League and Justice League Unlimited, Baloo on Tale Spin, the titular character on The Tick, Mr. Incredible on The Incredibles and Bird Man, a role that he hated with a passion.
On movies, he is the official Brazilian voice of Bill Cosby (awesome), Michael Caine (more awesome), Leslie Nielsen (even more awesome) and Clint Eastwood (Macho Man Randy Savage awesome) he also played James Bond in every movie until Pierce Brosnan took the role, then another actor was chosen for the role, but he didn't sound nearly as awesome.
On TV, he played Spock on Star Trek, which was awesome.
All in all, he is just plain awesome.
