A source from the crew spills the beans, "Zayed wanted to rope in his brother-in-law Hrithik Roshan for the cameo, but his dates were not available.
Dia told Zayed that they should approach Shah Rukh. Since they both have known him and have worked with him they decided to request him to do a special appearance. SRK, who has always valued friendship and is eager to help his friends agreed to do so."
Well, it must not have been easy to for Shah Rukh to say no since he has worked with Zayed in Main Hoon Naa and is also good friends with his brother-in-law Hrithik. Not to forget that ZK's sister Sussanne Roshan and Gauri Khan are best buddies.
"Since SRK is working on the post production of Ra.One and not shooting for any other project, he decided to squeeze in three days of shoot for their film. He will be shooting with them post July 15 at his place or at a Bandra five-star hotel, " informs the source.
