Uday and John have been friends since the time they did Dhoom together. They both have been biker buddies. It is learnt that it was Uday who made a call to John and requested him to do the guest role. John apparently plays himself in the film and there are constant references to John Abraham - the star in the film"s script. But it is learnt that John didn"t even care what his role in the film was before saying yes to it. He"s also adjusted his dates with other projects to accommodate Uday"s film, which needs only 4 days of his time."
Well, may be perhaps John Abraham knows that these 4 days may well be his re-entry ticket to Dhoom series Dhoom 3. Incidentally, Uday backed out of John Abraham starrer Hook Ya Crook as he was more kicked about his home production.
The Yash Raj project starring Uday has Priyanka Chopra and Dino Morea as well.
