Tanushree Dutta did not really strike it big in Bollywood and is best remembered only for 'Aashiq Banaya Aapne' (2005).

Now, as her sister Ishita Dutta is a new Bollywood aspirant, Tanu is keen that she doesn't repeat the same mistakes that she made.

Ishita makes her B-Town debut as Ajay Devgn's daughter in the upcoming film, 'Drishyam'. It apparently took director Nishikant Kamat just two days to finalise her after the auditions.

Ishita has done a few South films and a TV show as well.
