They may be a box-office success, but director duo Raj and DK's offerings are far from conventional. Which is why their next Bollywood outing, with Shah Rukh Khan, has our attention — who wouldn't like to see the perfect marriage of King Khan's mainstream appeal and Raj-DK's out-of-the-box ideas?

"It is our favourite script that we have held on to for a long time," says DK, adding that the duo was surprised that word of the collaboration got out. "We met him and discussed the script. He enjoyed the universe that the film belongs to. The story has elements that resonate with us," he shares, refusing to divulge further details.
