New Delhi, Jan 9 (IANS) Different storyline is the common thread that bound most Bollywood blockbusters last years. To cash in on the trend, Rajkumar Santoshi has rolled out 'Halla Bol' that has a 'strong' social message and the director is quite hopeful about its success.

'It is a good film, which discusses important social issues. It has all the elements to entertain the viewers,' Santoshi told reporters here Tuesday.

Ajay Devgan, who is playing the lead role in the film, added: 'Through our film we have tried to urge people to raise their voice against injustice. I hope it leaves an impact and people like it.'

The film is based on the late Safdar Hashmi, who was killed by political goons while trying to stage the street play 'Halla Bol' in Delhi in 1989.

Ajay, whose forthcoming projects include 'Sunday', 'Golmaal Returns' and 'U, Me Aur Hum', says as an actor he wants to do varied roles.

'It is not that I want to do only serious roles or comedies. As an actor I want to do an array of roles. In fact, it is not for me to decide which character suits me and which doesn't, audience decides it all.'

Commenting on selecting street play to promote the film, Santoshi said: 'Since the time of freedom struggle, street plays have been the most important medium to create awareness.'

'What could have been a better medium than this to promote our film? Also, we had thought that it would give a new life to one of the oldest art form of our country.'
