Vipul Shah's latest film "Waqt", whose promos have been released, promises power-packed performances from Amitabh Bachchan and Akshay Kumar.

With the film almost ready, Shah is marketing it in a unique way - with two different promos. One is "Waqt - The Film" and the other "Waqt - The Music". The film explores the father-son relationship.

Shah released two sets of greeting cards expressing the feelings of a father for his son and vice versa.
