The promos of both 1920 and Rock On look exciting and you can visualize an interesting story in that minute-and-a-half footage you've just watched.

Even in the film there are a few surprise actors in the film who appear in cameos. We had earlier reported that Naseeruddin Shah and Ratna Pathak Shah enact the roles of Imran Khan's parents in the movie. Well, there are three more stars enacting brief, but important roles -- Paresh Rawal [who enacts the role of a cop] and two Khans, who're brothers in real life. We're keep that a secret till Friday!
