Chennai, May 31 (IANS): Actress Sakshi Aggarwal, who has landed a key role in superstar Rajinikanth's upcoming Tamil actioner "Kaala", believes it's a golden opportunity to prove herself in a big film.

"Being part of such a big project means a lot to me. It's like a boon. Though I play a brief role, I'm thrilled about this film because it has given me an opportunity to prove myself as an actress, not just as a heroine," Sakshi told IANS.

"I have reached a point in my career where the size of the role doesn't matter. What really matters is if I'm making any difference to the project through my character," she said.

While she remains tight-lipped about her character, she is looking forward to share screen space with superstar.

"I met him at the photo-shoot. As a fan, I was awestruck and I will cherish this first meeting," she said, adding that her portion will be shot here and in Mumbai as well.

Being directed by Pa. Ranjith, the film's shooting is currently underway in Mumbai where the team will shoot non-stop for 40 days.

The film marks the reunion of Ranjith and Rajinikanth after last year's "Kabali".

Also starring Huma Qureshi, Anjali Patil and Samuthirakani, "Kaala" is being produced by Dhanush.
