"We have one item song in the film. Sonakshi and another top actress will be doing the song together. We are yet to finalise the other actress. These days, I believe, item songs are a great marketing tool," Shirish told PTI.
Directed by Kunder, 'Joker', is a fantasy-adventure film made in 3D format in Hindi, and stars Akshay Kumar, Sonakshi Sinha, Shreyas Talpade and Minnisha.
Sonakshi, who played a homely 'Rajjo' opposite Salman Khan in 'Dabangg', will be seen dancing to the tune of ace Choreographer Farah Khan for a raunchy item song. Farah would choreograph the song...it will be shot in Mumbai," Shirish informed.
"Both 'Munni Badnaam' and 'Sheila Ki Jawani' had set the box office on fire. We hope to break the record and do something much better. We intend to take a new approach for item song this time," Shirish said.
A R Rahman's nephew, G V Prakash, will compose the music for 'Joker'. This will be his debut in Hindi films, the director said.
Though the shooting is yet to start, Kunder is confident of his team.
"I think I have got the best possible cast and crew. I have put together a fantastic team for my film. I think I have won half the battle....The other half is execution. Hope I will manage to pull it off," Shirish said.
Though his directorial debut 'Jaan-E-Mann' failed badly at the box office, Shirish is looking forward for the upcoming film.
"I am directing a film after a very long time. 'Jaan-E-Mann' was shot five years back. The wait has to be worth it. I have to do something spectacular," Shirish said.
'Joker' is being jointly produced by Kunder and Farah's Three's Company, and Akshay Kumar's Hari Om Entertainment Company.
