While trade analysts and fans were eagerly awaiting the clash of action heroes Akshay Kumar and Ajay Devgn on June 6, news is that the release date of Ajay - Sonakshi starrer Action Jackson has been postponed. Though the new release date of the film hasn't been announced, it is being said that the reason behind this sudden change is the busy schedule of Ajay Devgn. Apparently, his next film Singham 2 is all set to go on floors this month while certain portions of Action Jackson are yet to be completed. Hence the filmmakers require some more time and do not want to hurry with the release date of the film. Produced by Gordhan Tanwani, Action Jackson is directed by Prabhu Deva and it also stars Yaami Gautam and Kunaal Roy Kapur.
