Development and casting Director
Vipul Amrutlal Shah wanted to make a film about a father-son relationship that would be different from "standard Bollywood father-son" stories. Shah wanted to explore nuances of the relationship and touch upon themes about a father-son relationship that is grounded in reality, which had not yet been depicted in Bollywood. Kapadia, who had co-written Shah's 2002 heist thriller
Aankhen with him, adapted his play for the screen. Shah said of the film's theme; "It is an unusual story of a father and a son. It is very, very real and believable. I can assure you that any father-son duo of any economic strata will be able to identify with the father and son in my film." Shah said he felt the film's title suits its theme perfectly, saying "
Waqt is called
The Race Against Time because there is a target that both father and son have set out to achieve, and for that they've got limited time. So there really is a race against the clock. If they don't achieve their targets in that time, life will take a very disastrous turn. They each have their own target." It was the first major co-production for Eros International. Shah cast the film's six main characters. In late May 2003, he said he had cast
Amitabh Bachchan and
Akshay Kumar, both of whom starred in his previous film
Aankhen, as the father and son characters and that he hoped to cast his wife
Shefali Shah as one of the film's two female leads.
Rajpal Yadav and
Boman Irani completed the cast. The director wanted to cast a female actor who had not been paired opposite Bachchan before and while discussing potential contenders for the role, Bachchan suggested Shefali, who he thought would be perfect for the role. He said, "I was attracted to just these facts—how these relationships have been built up; and how the interactions, the situations, are brought up; what the characters do, how they behave; the events that take place; and the eventual solution". Kumar said it was his "most personal film" and that he worked "very honestly" on it. According to Kumar, at one point he was in talks to produce the film with Shah but it could not work out. Shefali said the film's strengths are its "simplicity and honesty", and that she found playing a fifty-year-old woman whose life revolves around her child and husband to be challenging. She felt her character is strong and different from the mothers usually portrayed in Bollywood films, saying: She is someone who has come up the hard way in life and understands the importance of whatever her husband has achieved. She wants her son to understand that and stand on his own feet and achieve what her husband has been able to achieve. Her ability to laugh at situations and her sense of humour when her world is falling apart is her strength. Irani called his character a "loud, brazen, shameless, egotistical" man who "keeps reminding [Bachchan's character] that his son is a useless character because he himself has a wonderful daughter"; he found the character easy to portray, saying he "is a reasonably an easy connect because we do have so many people like that around".
Vikram Phadnis designed the costumes for the actors. Several scenes were shot out of chronological order; the scenes based in one particular set were filmed together to save time. The songs were choreographed by
Remo D'Souza. Bachchan, who has featured in a number of
Holi songs in his film career, does not appear in the film's Holi number "Do Me A Favour, Let's Play Holi". Shah tried putting Bachchan in the song but decided it did not fit in the script, calling it a "tough decision". Chopra had an accident while filming the Holi song; The set was wet and so was Chopra while filming the Holi dance sequences. After the choreographer called for break, Chopra went to dry off in the trailer and she was electrocuted as she turned the door knob. Her hand stuck to the knob but her hairdresser knocked her away from it. After the incident, Chopra was unconscious and was rushed to the nearby
Lilavati hospital. After two hours, she returned to the studio to complete filming the same night. In early December 2004, Shah said he was looking for another 20 days of filming before wrapping the film, followed by three to four months of post-production and an April 2005 release. The film was edited by
Shirish Kunder. == Soundtrack ==
