Alec Baldwin, Anjelica Huston and Kellan Lutz are among the stars who have signed a petition urging McDonald's bosses to adopt a less cruel chicken slaughter method.
The trio was among the stars who agreed to be part of the PETA 30th anniversary petition.
The stars want McDonald's chiefs to heed the advice of the company's own advisory board and switch to the much less violent chicken slaughter method that McDonald's already uses in Europe.
According to PETA, McDonald's suppliers cut chickens' throats while they are conscious and scald birds to death in defeathering tanks.
The celebrities who signed the petition also include Isabel Lucas, Olivia Munn, Eli Roth, rockers Iggy Pop and Dave Navarro and longtime PETA supporter Pamela Anderson.
