Though Ajay Devgan has said that he has nothing against Shahrukh Khan, but it seems the former is trying to gain publicity by accusing Yash Raj Films of blocking screens for his film, Son of Sardar, which is scheduled to be released on November 13, same day when Jab Tak Hai Jan hits the theatres. Calling the controversy 'silly and strange', Khan has said that it is a 'free market', depending on exhibitors which film to buy.
