A social activist from Pune has accused Amitabh Bachchan of promoting superstitious beliefs in the new commercial ad for the health drink - Complan. Big B plays 'takat ka bhoot' (Ghost of energy) in the advertisement.Activist Hemant Patil has filed a complaint before a court seeking action against the Bollywood actor. Hemant Patil has demanded a police complaint against Bachchan and others under the stringent new Maharashtra Prevention and Eradication of Human Sacrifices and Other Inhuman, Evil and Aghori Practices and Black Magic Act, 2013. The immediate provocation for the complaint was Bachchan's portrayal of a ghost in a TV commercial for a children's health drink. Mumbai magistrate Sita Kulkarni has placed the matter for hearing April 18. Bachchan has earlier played a friendly ghost in Bollywood movie Bhootnath, whose sequel Bhootnath Returns is due for release this April. "The advertisement promotes belief in the existence of ghosts and spirits and consequently the need for magic to ward them off. This is promoting false beliefs and promoting superstitions," Patil said. He further said that when he tried to file a complaint with police in Bandra, they refused, compelling him to move the court. Patil also said the health drink company released the TV commercial without adding an appropriate disclaimer before or after the broadcast.
