Phoenix walks the line "cruelty-free"

Phoenix has big shoes to fill in his role as Johnny Cash. However, msnbc.com reports that when he fills those shoes he will do so "cruelty-free"

When Joaquin Phoenix walks the line in a Johnny Cash biopic, it will be in plastic cowboy boots. The moody actor is a staunch animal-rights supporter, and drove the wardrobe folks a little batty by insisting on wearing an entirely "cruelty-free"wardrobe, says a source.
