Kalishankar or Kalisankar is the bilingual film in Oriya and Bengali language by director Prashanta Nanda in 2007. This Bengali- Oriya film is a remake of Rakesh Roshan's film Karan Arjun on the theme of reincarnation. Director Prashant Nanda turned the story around: Instead of being the story of the offspring (played by Salman Khan and Shahrukh Khan in the original) it is the story of a pair of grandchildren and their grandfather's revenge on their wrongdoers. He plays the grandfather. The film has much stick-wielding action. Kalishankar is similar to old Manmohan Desai films wherein brothers separated in childhood grow up to find themselves on two sides of the fence. Then, when they recognise their blood link through a birthmark or a talisman, they join forces to fight the enemy together.
