According to Anushka, 'Salman Khan's fans says that they are her fan too, this is a big thing because they are very loyal fans. Three khans have such loyal fans. So, she is feeling very special. Anushka said, 'I think you want people to see at your work and should be appreciated and it happened in the film. I'm very happy.' Appreciation is special for Anushka, because according to her it was a challenging film. Anushka believes that she worked like robot for her physical change and worked hard to understand Aarfa's thinking, that got successful. Anushka said, 'Sultan has been most difficult film for me so far. This was challenging for me, Physically and emotionally it was difficult for me.
