MUMBAI: You’ve seen Saif Ali Khan get sentimental about his guitar and hang it on a freshly painted Asian Paints wall. Now sister Soha will join Saif in the new Asian Paints Royale commercial.

The ad film, yet to be shot, will follow the old formula and will have an emotional story line. According to a source, the film, in all probability, will have the duo reminiscing childhood memories.

When contacted, Asian Paints’ advertising agency Contract and ad film production company Highlight Films refused to comment, saying, “We are in no position to give out any information.”

Asian Paints’ spokesperson was equally non committal with a “There’s nothing to be spoken about this.”

Saif’s forthcoming film will be Eklavya directed by Vidhu Vinod Chopra, which is slated for a release next year; while Soha will be seen in Sanjay Gupta’s Dus Kahaniyan. There were talks of the two starting a production company, which finally fell through. This will be the brother-sister duo’s first on screen appearance together.
