Sources indicate that Shah Rukh Khan's film contract reportedly made two things clear.According to a report in Times of India.
One: The actor will not lock lips with his heroine on screen.
Two: he will not ride a horse. The second condition came into being after SRK experienced severe back pain a few years ago.
On the other hand, Ajay will be seen riding not one but two horses in his Son Of Sardaar.
Some other facts on the SRK-Ajay films that are expected to lock horns this Diwali are:
Shah Rukh's friend and business partner Juhi Chawla is one of the leading ladies of SOS. Uday Chopra's ex-girlfriend Tanisha Mukerji is the executive producer on the Ajay film. SRK's close business associate Kishore Lulla has bought the worldwide rights for SOS.
Clearly the two projects seem to be interlinked.
