Shah Rukh, Rituparna Sengupta to play couple

Bollywood superstar Shah Rukh Khan and Bengali actress Rituparna Sengupta will be seen as husband-wife in an ad for Emami's health product Chyawanprash.

Shah Rukh will play a commoner in the ad and for the first time will be seen with Rituparna. If a source is to be believed, the actress was "super excited and nervous" about working with the superstar.

The ad film will be directed by Ram Madhvani of Equinox FIlms who had earlier directed the song Bheja kum in Taare Zameen Par.

It will go on air towards the end of October.
