The movie is directed by Leena Yadav and produced by Ambika Hinduja under the banners Hinduja Ventures and Serendipity Films.

In London to shoot for the last schedule of "Teen Patti", Amitabh completed five scenes at an "exotic casino" with the Oscar-winning star.

"(It's)...a joy really to be working with a crew that respects efficiency and time and a colleague who is professional to the core," Amitabh wrote on his blog www.bigb.bigadda.com.

"It's been a joy to work with Sir Ben. He is generous and polite, prepared and competent and cooperative with every breath. It is no wonder then that we have finished what would have involved us all for several more days," he added.
