Ali, 27, who is known for his portrayal of Joy Lobo in '3 Idiots', apparently wants to be an active part of the movie's promotions along with co-star Vidya Balan.
Balan has been visiting different cities to spread a buzz about the film, directed by Samar Shaikh and produced by Dia Mirza and her fiance Sahil Sangha.
"Ali, in fact, has been trying his best to make it for 'Bobby Jassos' promotions but he has to stay back on the sets to shoot. After a lot of shuffling, Ali has managed to get only a day or two off from 'Khamoshiyan' to promote his latest release, which will be his biggest film so far," a source said.
