Tanuja Chandra feels that the unique chemistry between Sushmita Sen and Shiney Ahuja is the highlight of her forthcoming film "Zindaggi Rocks".

"It is something to watch out for. Honestly speaking, I never expected their chemistry and timing on screen to be so perfect. Sushmita is a huge on-screen personality but that hasn't deterred Shiney from striking a great equation with her," said Chandra, who signed Shiney much before the release of "Gangster".

"It was much before he walked away with all the awards. I signed him out of pure instinct knowing that he would make it one day and my intuition has proved to be right."

The song picturisation of Chandra's "Zindaggi Rocks", which was cancelled following Sushmita's back injury, is likely to start shortly.

"The song had some very complex twists and turns and Sushmita unexpectedly had a back sprain while performing it. She has been advised two weeks rest but I am expecting her to be back on her toes before that. She's all excited about the film and has been giving her best shot," said Chandra.

The film is complete apart from the song and a day's shoot.
