Our film industry has two kinds of stars - star kids and self-made stars - and, obviously, star kids get many more opportunities than the other variety of stars. So this film was being made which featured a star kid and a self-made actor.
The producer and the director were struggling with the film as there was no bound script, and since locations had not been decided in advance, they were shooting in bits and pieces. While the self-made star never once uttered a word and kept adjusting his dates, the other star decided to opt out of the film as he believes in tight schedules and bound scripts. The actor has still not allotted any dates and has since signed some more films.
