Rakul Preet Singh is looking forward to putting in loads of homework before she starts shooting for her role in 'NTR-Kathanayakudu' (releasing on Jan 9). In this NT Rama Rao biopic, Krish Jagarlamudi is casting her in the role of the legendary Sridevi.

Speaking to an English-language daily, the 'Dhruva' and 'NGK' actress reveals that she will give a series of look tests in the near future. The director will okay a couple of looks, it seems.

The makers have asked the star actress to watch particular movies of the late Sridevi. Rakul has already watched some of them. She wants to get the body language of the late superstar-actress perfect.

Besides 'De De Pyar De' in Hindi, Rakul is also doing Suriya's 'NGK' (Telugu and Tamil), a Tamil film with Karthi, and another Kollywood project with Sivakarthikeyan.
