Peter Griffin is one of the biggest characters on television today, both literally and figuratively. Nobody could mistake his distinctive voice for someone else. Played by Seth Macfarlane, you'd think the job of doing Peter's voice would be enough. Not for Macfarlane, though. He also does the voice work for Brian and Stewie on Family Guy, as well as Stan and Roger on American Dad.
Macfarlane first started out as an enthusiastic nine-year-old who had one of his comics published in his local newspaper. He then went on to become a writer and animator for some of our favorite '90s cartoons, including Johnny Bravo, Cow and Chicken, and Dexter's Laboratory. He was a consistent worker, but it wasn't until Family Guy that he really started to shine, and we're so glad he did - we love that show!
