Apparently Kalki and Emraan Hashmi have been paired again in an upcoming film, even before their first movie 'Shanghai' together hits the theatres.

Even before their first film together Dibakar Bannerjee's Shanghai hits the marquee, Emraan Hashmi and Kalki have bagged yet another film together. Buzz is that Kalki has been cast as the witch in Vishal Bhardwaj-Ekta Kapoor's Daayan opposite Emraan to hike the curiosity factor.

Our source says, "Both Emraan and Kalki have done different kinds of movies, more so unlike each other's kind of subjects." And though in Shanghai, Kalki has more scenes with Abhay Deol, the makers of Daayan thought bringing together the actress and Emraan would make the pairing more interesting.

Our source points out that after starring in films like Murder, Murder 2, Jannat, Raaz - The Mystery Returns, Emraan has been exploring diverse characters in films like Once Upon A Time In Mumbaai, The Dirty Picture and now Daayan and Ghanchakkar.

"Kalki has won her own audience after films like Shaitaan and That Girl In Yellow Boots. Also important to note is that she fitted the part perfectly.

So considering that they're poles apart in their choice of films so far and the images they have, the two together seem an interesting onscreen pair. Just like Emraan and Vidya Balan in Ghanchakkar after The Dirty Picture," explains our informer.

Also, buzz is that two more actresses are yet to be finalised for Daayan that is being directed by Kanan Iyer, erstwhile assistant of Vishal Bhardwaj.
