Adam Savage, the host of "MythBusters" on the Discovery Channel, is a longtime special-effects artist and a minor obsessive.
As his official MythBusters bio puts it, "Adam Savage has spent his life gathering skills that allow him to take what's in his brain and make it real." He worked as a special-effects artist, fabricator, modelmaker and general dreamer-upper for a decade and a half, working on films such as Galaxy Quest and the Matrix sequels, as well as Episodes I and II of the Star Wars series.
In 2002, he and his fellow movie-industry veteran Jamie Hyneman became the hosts of MythBusters, a Discovery Channel show that puts urban myths and rules of thumb to test in visceral, often hilarious ways. Behind the sheer awesomeness of their rocket cars and flaming projectiles, the MythBusters are a force for science education.
