London: The anti-smoking campaigners are upset over Johnny Depp's animated movie 'Rango' for glamourising smoking onscreen.

The movie, which features the voices of Depp, Isla Fisher and Bill Nighy, follows a group of chameleons searching for water that has been stolen from a town called Dirt.

The activists claim the images of animated lizards and birds puffing on cigarettes pose a risk to children, who are usually the target audience for animated movies.

Stanton Glantz, director of the Center for Tobacco Control Research and Education at the University of California-San Francisco, says, "A lot of kids are going to start smoking because of this movie."

Campaigners now want movie chiefs to add a Surgeon General's warning to the project.

A spokesperson for movie studio Paramount, Virginia Lam, insisted they never meant to condone smoking and they ensured the main character isn't seen puffing away.
