Karan Johar had signed up late Bollywood actress Sridevi for his production venture, Abhishek Varman directed ‘Shiddat’. Rumours are rife that the filmmaker is looking for a replacement and is planning to approach Madhuri Dixit to fill in the role. A source close to the filmmaker revealed, “Karan was extremely fond of Sridevi and they shared an amazing relationship. He doesn’t want to rush to find a replacement right away. That is certainly not on his priority list. It’s just two weeks since Sridevi’s death. Karan will soon sit with the team and will decide who they want to approach for the role that was offered to Sridevi, all other speculations are baseless.”
