The Grey actor Liam Neeson has entered into the bad book of animal right activists, who claim that the actor's act of dining on wolf flesh will endanger the species.

Furious over the movie and its message, animal rights group PETA has called for a boycott of Neeson's survival thriller The Grey, according to a Daily Mirror report.

The movie grossed $20 million in the opening weekend and still tops the box-office collections, according to a Businessweek report.

The British actor and his fellow cast and crew from the movie reportedly had stew made of wolf flesh at the insistence of movie's director Joe Carnahan.

The movie is about a group of people stuck in the Arctic, after surviving a plane crash. Neeson is the leader of the group, which is hunted down by a pack of wolves in the movie.

During the making of the film, director Carnahan wanted his cast and crew to get into his/her character in the movie in a real way. He insisted the cast to dine on wolf meat sourced from a trapper, according to a contactmusic.com report.

The People for the Ethical Treatment of Animals is not impressed with Carnahan and Neeson's realistic ways.

The PETA condemned the act and called for a boycott of the movie. It called Liam Neeson no friend to animals and said, Don't just shy away-run away from The Grey.

The animal right groups and the experts see red over the portrayal of wolves as man hunters in the movie. Wolves are not man hunters and are intelligent family oriented animals with high ethical and moral standards, according to Krupaker and Senani who directed the Green Oscar-winning Documentary The Pack. 

The animal right activists and the wildlife experts believe that the film and crew's wolf dinner might further endanger the existence of the wolves in the world. The species are already in endangered list in many states in the U.S.
