Sanjay Dutt will next be seen in Siddharth Anand's upcoming untitled movie, and the actor has been training hard to learn the nuances of a special form of martial arts. Sanjay is being trained by Shifu (Master) Kanishka Sharma and the director said that such training is usually imparted to National Security Guard (NSG) commandos.

"It's a rigorous and intense form of martial arts that NSG commandos train in, and which can help them kill a man with bare hands in just three moves," Mumbai Mirror quoted Siddharth as saying.

The "Bang Bang" director, who has been working on the script for the past six months, also said the training would continue till the end of June. Sanjay undergoes training for four hours every day, and also does freehand exercises, rather than going to the gym, the report said, adding that Sanjay would sport a spiked haircut and a French beard in the film.

Siddharth's last directorial venture "Bang Bang," starring Hrithik Roshan and Katrina Kaif, was a big box office hit, and now the director is gearing up for another action-oriented film. Sanjay recently completed his jail term and is now eyeing some good movies, and will not do any film out of compulsion, the report said.

After doing Siddharth's film, Sanjay will collaborate with Umesh Shukla for another movie. "When I had narrated him for the first time, he had liked the idea. After he came back from jail, I met him and we discussed about the film. He said 'Let's work out.' We are developing the subject. I think he will first start shooting for Siddharth Anand's film, then he would shoot with us. The film will happen next year," Shukla had told Press Trust of India.
