LOS ANGELES (AP) - In "Game of Thrones," Peter Dinklage's character is constantly steeped in battle over control of a mythical kingdom. After the show's season finale on Sunday, Dinklage plans to take his fight to the farm.

Dinklage, 42, will spend his off season promoting a campaign to change the way society treats farm animals as national spokesman for Farm Sanctuary's annual Walk for Farm Animals.

The actor, who has been a vegetarian since he was 16, has won an Emmy and a Golden Globe for his role in the HBO series. He said he joined the cause because he felt "animals used for food are treated like unfeeling machinery."

Farm Sanctuary, which provides care for more than 1,300 rescued farm animals, will put on walks in more than 35 cities across the country this fall.
