In 2006, Anderson starred along with his bear Brutus in "Expedition Grizzly," an episode of the documentary series Wild for National Geographic Channel. The episode, for which Anderson was also associate Producer, focused on his relationship with Brutus and a year-long project they undertook to observe and understand the habits of wild grizzly bears living in Yellowstone National Park. He subsequently became the regular host and Producer for the long-running wildlife documentary series Expedition Wild, which has covered many different animals including mountain lions, wolves, wolverines, and several species of bears. Some episodes have also focused on the wildlife of particular areas such as Yellowstone and the Grand Canyon. Originally airing on the National Geographic Channel and later on its sister station Nat Geo WILD, Expedition Wild has been widely syndicated, including on ABC as part of Litton's Weekend Adventure, on The CW, and online via Hulu.
