Sana was asked by Vishal to rehearse with a violinist for a shot in the film, Wajah Tum Ho. When it came time to shoot the scene, Sana told Vishal, “I am sorry but I didn’t rehearse.” The violinist backed up her story and told Vishal that Sana was unable to do it.
Vishal was left with no choice but to go ahead with shoot and see how it turns out. When they started the shoot, Sana played it so beautifully and the director was stunned with her. Then he realized that Sana was playing a prank on him. The bit she played will be seen in the film.
