Directed by Rohit Shetty, 'Bol Bachchan' is a romantic comedy inspired by the 1979 comic flick 'Golmaal', which was directed by Hrishikesh Mukherjee and starred Amol Palekar, Utpal Dutt, Bindiya Goswami and Dina Pathak in pivotal roles.
"Initially a lot of people said that there is no need to buy the rights of 'Golmaal', but I believed that if you are inspired by a film, it is ethical to buy the rights," Ajay said.
"As the film has inspired us, so it is like giving tribute. It is about ethics and business. Ethics are important and if we do not follow it we can't expect others to do it," he said.
In the newer version of the film, Abhishek Bachchan essays the role played by Amol Palekar in the original while Ajay Devgn's character is similar to that of Utpal Dutt.
"Character wise (that I play) there is no similarity, it is a 40-year-old film. When you adapt an old film I think everything changes completely. The base idea of one person playing two people is same. It is a sweet film," Ajay said.
In 'Bol Bachchan', Ajay plays the role of a wrestler and Prachi Desai is his sister. "I play a wrestler from a small town and he has this fascination towards English. He feels he is speaking very good English but he speaks it wrong and no one corrects him as people are scared of him. He believes in honesty," Ajay said.
"For this character I had to put on a little weight. In 'Singham' I was very lean. Since I play a wrestler in this movie, I have muscles so I had to gain a little. I don't have any inhibitions. Whatever suits the character I am ready do it," he said.
The film is slated for release on July 6.
