Amitabh Bachchan has roles in two up coming films: Rann and Teen Patti.  Rann is about a media mogul and will be discussed in another post.

Teen Patti is a story about two mathematicians who meet in London.

Venkat tells Perci about an equation that could not only change the dialogue on mathematics forever, but one that has already left an indelible impression of guilt - for many painful reasons - on Venkat’s life. As it turns out, the reclusive genius Venkat has cracked a theory that could redefine the principles of probability and randomness.

Ben Kingsley also plays a crucial role in the movie.  Ben Kingsley is the mathematician that Amitabh meets in London, and from which the story ensues.

Look forward to this movie and Rann in the coming future.
