Keeping up the suspense, superstar Shah Rukh Khan today said no decision has been taken on who will be cast opposite him in filmmaker Imtiaz Ali's next venture, amid rumours of actress Anushka Sharma being on board for the movie.

Since Shah Rukh made the official announcement on the film in March, gossip mills have been abuzz with stories that the 50-year-old actor will play the role of a Sikh guide and reunite with his "Rab Ne Bana Di Jodi" co-star.

"I have been hearing a lot of things like I am playing a Sikh, a guide... But in another two months we will announce the whole film. We are just waiting for the technical team to get together," the "Fan" star told reporters here.

When asked about re-teaming with the 28-year-old "Bombay Velvet" actress, Shah Rukh said, "We have some technical issues, trying to decide who all are going to be part of the film. So we have to wait."

The project will mark Shah Rukh's first collaboration with the "Tamasha" director, who has long been a fan of the star and often expressed his desire to make a film with him.
