Inspite of critics bashing up his last release 'Bang Bang', director Siddharth Anand managed to deliver a box-office hit that starred Hrithik Roshan and Katrina Kaif.Always known for his impeccable casting, Anand has taken the industry by surprise with the casting of his latest film, 'Marco'.If sources are to be believed Sanjay Dutt has been roped in to star opposite Kriti Sanon.While Dutt was last seen in Aamir Khan's immensely applauded 'PK', Kriti appeared recently on Shah Rukh Khan's much disappointing 'Dilwale'.A 50-plus Dutt and 20-something Kriti, sure make for an intriguing cast.Perhaps we would to have to wait to know the story behind the casting.
