Call of the Wild (also known as Call of the Wild 3D, titled Buck in Australia and New Zealand) is a 2009 American 3D adventure drama film starring Christopher Lloyd, Timothy Bottoms, Veronica Cartwright, Christopher Dempsey, Joyce DeWitt, Aimee Teegarden, Ariel Gade, Devon Graye, Devon Iott, Kameron Knox, Russell Snyder, and Wes Studi; and directed by Richard Gabai.

A recently widowed man, "Grandpa" Bill Hale, in Montana takes his granddaughter Ryann in for several weeks while her parents are out of the country.

When a wild wolf-dog hybrid shows up injured on the back porch one night, Ryann decides to take the wolf, whom she names Buck, named after the Jack London character, back to Boston with her as a pet, but Grandpa knows Buck will eventually have to return to the wild.

They challenge Ryann and her grandfather's neighbor, a teenager named Jack, to a dog sled race.

Over the course of two weeks Jack trains Buck to be a lead sled dog, while Ryann's grandfather reads her The Call of the Wild.
