Salman Khan,the Bollywood superstar is often known for his laid back and relaxed attitude but astonishingly director Ali Abbas Zafar says he was completely dedicated while working on Sultan.

As per the Ali said, "He (Salman) was not laid back at all. On paper, he knew he can't afford to be laid back as he had to work hard for this film as he is racing against a steam engine...In wrestling, weight goes up and down. Physically, this film has been very challenging,"

“Even after going through the grueling training sessions and workouts in the gym, according to Ali, the 50-year-old actor never complained Only on hard days he used to say can I have an ice cream... But the day he was done he had four ice creams," Ali added.

Sallu had to change his weight from 100 kgs and then as per the orders of Ali, he came down to 90 kgs and then to 82 kgs."At the age of 50 to do all this within six to eight months takes a lot of hard work.

"Even when he was not working on sets he had to train for four hours. This is phenomenal for an actor enjoying such stardom," he said.

He added, "This is Salman's first sports film and you do make some changes keeping his personality in mind. We wanted to make Sultan with him only. Whatever changes happened, it happened on the sets not on script level,"

"His understanding and experience helped us to make a better film. He did small changes and not the big things," he added.
