Salman Khan was once known for his whims and erratic schedule at work but he had turned his life around and had come to be very systematic in his approaches. Strangely, he hasn't been himself lately.

According to a SpotboyE report, the superstar has been cancelling his "Sultan" shoots at random. Apparently, he calls the unit at the 11th hour saying he will not be able to make it to work on the day.

Quite obviously Aditya Chopra and director Ali Abbas Zafar are clueless as to how the situation can be managed. Meanwhile, the film's leading lady, Anushka Sharma, is all set to shoot a romantic sequence with the 50-year-old actor.

The two along with Randeep Hooda will jet off to Ludhiana, Punjab in March. The sports-drama is expected to be shot across Kila Raipur and Gujjarwal villages. Interesting bit is, Aamir Khan's "Dangal" has also been filmed in these areas.

In other news, the much-written about "Sultan"-"Raees" may not happen, thanks to Ms. Sharma. Both the films were blocked for Eid this year. "Sultan' and 'Raees' won't clash on Eid anymore. Aditya Chopra and Salman Khan took a long time in finalising the leading actress of the film, and though Salman has shot for various portions of the film already, a lot of shots and post-production work are still pending," BollywoodLife quoted an insider as saying.
