Sanjay Dutt is being cautious about his Bollywood projects after the debacle of his last release, ‘Bhoomi’. The actor has been opting out of several projects, which also includes the recently announced ‘Blockbuster’. If buzz is to be believed then Dutt has decided not to be a part of the multi-starrer comedy film which was to mark the directorial debut of his close friend Lovel Arora. Earlier, Sanju had walked out of Abhishek Varman’s next, in which Madhuri Dixit replaced the late actress Sridevi. The ‘Khalnayak’ duo was to share the screen space after two decades.
