We have already reported that the makers of Kalam are super-thrilled to rope in a popular veteran actor for a significant role in the film but they do not want to spoil the surprise by revealing the name. Now, here is another interesting tidbit--an ancient house with 10 doors plays an important role in this unique script.

Apart from this actor, the suspense thriller also stars Lakshmi Priya, Amzath, Shrini and Pooja in lead roles. A house where most of the movie was shot plays the central part of the movie. The film is directed by Robert Raaj and Arul movies production is bankrolling it.
