Thirumurugan Gandhi, a Chennai based activist, has slammed forthcoming Bollywood movie 'Madras Cafe', insisting that the film portrays twisted historical facts

Gandhi also insisted that the cast and crew of the controversial film, which is based on political and military histories of India and Sri Lanka, should come forward in an open debate.

Since the movie is based on the history of Tamils, they are entitled to have a say in the matter, Gandhi said.

The flick, which is set to release across India on August 23, also covers intelligence agencies and Lankan rebel group LTTE.

Gandhi said that the film took a historical incidence and twisted it in such a way that it portrays a wrong impression on what was meant on the Tamil Elam.

Pro-Tamil outfits and various other political parties in the province also objected to the release of actor John Abraham's movie, after the movie was shown to select Tamil activists on Sunday.
