Amisha Patel is playing the character of a mother in 'Tathastu'. And Sanjay Dutt is playing her loving husband in it. She says, "This is not the first time I'm playing a mother - I've done it before in Gadar and frankly, I find it no big deal to play a wife, a mother or young college girl. Yeah, there are cosmetic changes. After all, I can't be a desi blonde mummy, right? So, I had to color my blonde hair back to brown, for this role only."
