Rohit Shetty directed Ajay Devgan and Abhisheik Bachchan together after 9 years. They both were part of his first film "Zameen" (2003).

The film is inspired from 1979 Hrishikesh Mukherjee's classic Goolmaal staring Amol Palekar and Utpal Dutt with Bindiya Goswami.

On Dussehra 2011, director Rohit Shetty who previously directed the comedy flick, Golmaal 3 (2010), did first give actor Ajay Devgn an offer for Golmaal 4, but Devgn claimed "Golmaal 4 will happen next to next year. It's necessary to have two years gap between two Golmaal films. It's not good if it comes every year." After the announcement, it was added that Bol Bachchan will be made before Golmaal 4.
