Karan Johar, who has acquired the movie rights of Amish Tripathi's bestseller "The Immortals of Meluha", says he is yet to finalise the director for the big screen adaptation of the bestseller.

"People been asking about the 'Meluha' book... we are going to lock a director first... then start the screenplay work and then cast LORD SHIVA!" Johar posted on his Twitter page.

"The Immortals of Meluha" is the first in the Shiva trilogy series by Tripathi and it is the story of Shiva, a Tibetan refugee who is taken to Meluha as the king of Meluha believes in the legend that an outsider will be their saviour.
