This was first of the two clashes between the Big Ms in 2007. This was also the clash between two of the best directors among the new generation filmmakers. Chotta Mumbai (April 06, 2007), directed by Anwar Rasheed, was an in and out masala laughter riot. On the other hand, Big B (April 13, 2007), directed by Amal Neerad, was first of its kind action thriller in Malayalam. This movie also gave a new dimension, in the aspects of technical perfection and storytelling, to the gangster films genre in Malayalam. Both the movies were mass films and did good business at the BO. But the winner in this case was Chotta Mumbai, which went on to become one of the top among Mohanlal box office hits.
