Abhishek surprised the Unit members of Farah Khan's Om Shanti Om a few days ago.

Even as the supposed war between Shah Rukh Khan and Amitabh Bachchan continues to gain momentum, the ever-courteous Abhishek Bachchan dropped by the sets in Film City to meet Shah Rukh and Farah.

"Abhishek was shooting for an ad film for Motorola in Film City, very close to where OSO was being shot, so he dropped by to meet SRK and Farah. They exchanged pleasantries and chatted for about 15 minutes before Abhishek left." Says an eyewitness present at the location.

Apparently the vibes between the trio were warm and cordial. It was a spontaneous decision by Abhishek to drop by Farah's sets.

Whenever Shah Rukh and the Bachchans have met at social events, they have been cordial with each other. In fact, When Abhi came to the sets, Farah asked him to play a walk-on part and he has agreed. Karan Johar, Subhash Ghai and Rishi Kapoor are some of the other people who are doing cameos in the film."

Produced by Shah Rukh's Red Chillies Entertainment, Om Shanti Om stars Shah Rukh Khan, Deepika Padukone, Arjun Rampal, Shreyas Talpade and Kirron Kher.
