"I wish I could do Chulbul Pandey but this ('Department' role) is something different. 'Department' talks about police department. It is a real story with real characters. It is about two cops, while one works with values and principles, the other is completely opposite," Sanjay told reporters here Monday.
"It's a commercial film but it has a meaning to it. I couldn't play Chulbul Pandey or Singham (Ajay Devgn's role in 'Singham') in it," he added.
The actor was here for the promotion of "Department", which hits the screen May 18. Sanjay was accompanied by co-star Rana Daggubati and item girl Nathalia Kaur.
The movie also features Amitabh Bachchan in a pivotal role.
