Seema has been doing un unbroken series of stern wretchedly unhappy characters including the unforgiving mother in Sooraj Barjatya's Vivah and the profoundly grieving widow in Deepa Mehta's Water.

Deepa has been going through her own bouts of depression after shooting the story of a battered wife in Heaven On Earth.

Both Biswas and Mehta ere ready to whoop it up with a comedy.

"It a film called Stella about a joyous adventures of a wacky nanny. I just thought Seema was so right for it. So far we've only seen her in serious roles.

Seema has an innate sense of fun and mischief which nobody has tapped," says Deepa even as she wraps up Heaven On Earth with Preity Zinta in Chandigarh.

Stella starts shooting in January 2008. "I'll be co-directing the film with my brother Dilip Mehta. Before going into my next big project Luna with John. I hate to praise my own family. But Dilip is a very talented filmmaker," informs Deepa
