Bob Barker and The Simpson's co-creator Sam Simon have teamed up to spearhead a new animal rights campaign to keep creatures safe from harm on movie and TV sets. The two celebrities have joined People for the Ethical Treatment of Animals activists in calling for the reform of the No Animals Harmed... label given to film projects that are given the American Humane Association (AHA)'s stamp of approval whenever horses, dogs, cats and other furry friends are used.
