Yash Chopra said the as-yet untitled film will star Shah Rukh Khan and Anushka Sharma, as well as Katrina Kaif, with music from the Oscar-winning "Slumdog Millionaire" composer A.R. Rahman.
The 78-year-old, whose last stint in the director's chair was with Veer-Zaara in 2004, says he thought long and hard about returning to the studio floor and admits he has no idea whether it is the right move.
Chopra is hoping that bollywood king Shahrukh khan and Sharma will provide a winning formula. They were last seen in the 2008 hit "Rab Ne Bana Di Jodi", produced by his Yash Raj Films company.
