In the 1996 film adaptation, he was portrayed by Deano Clavet.
During Buck's life in Santa Clara Valley at Judge Miller's place, he is stolen by the gardener's assistant named Manuel and is sold to the Baggage Man to Seattle. When Buck looked out of the car and realized that his life would never be the same, he attacked his kidnapper, but the baggage man tightened the rope around his neck and swung him to the ground before kicking him. The baggage man went for his throat, but Buck dodged it and bit the man's hand. However, the baggage man choked him once again and has decided that he has fits, so he decides to take him to a saloon-keeper in San Francisco.
The saloon-keeper buys Buck from the baggage man and he unwrapped his wounds as the other men throw Buck into a crate. A few smugglers come and pick up the crate onto the wagon as they continue to torment Buck. For two days, they continued to torment and starve Buck until they arrive at Seattle, where Buck was taught the law of the club by The Man in the Red Sweater.
Buck is then later sold to a pair of French-Canadian mailers named Francois and Perrault and he, along with Curly, are taken to the Yukon on the Narwal.
- In the 1996 TV movie The Call of the Wild: Dog of the Yukon, Buck is sold to the Man in the Red Sweater after the Baggage Man, instead of being sold to a saloon keeper then the Red Sweater.
