Om Shanti Om was made on a budget of Rs400 million. The first scene to be filmed was one where Talpade's character tells Shah Rukh's character that he will be a hero; Shah Rukh was an hour late for filming. Farah was pregnant with triplets while filming and experienced difficulties while shooting, she would constantly vomit while directing the film. The film was shot entirely in sync sound; Farah dismissed rumours of Padukone's voice being dubbed. In 2015, however, Mona Ghosh Shetty admitted to have dubbed for Padukone in the film. Afake fight scene involving a stuffed tiger was inspired by a similar scene in the film Tarzan 303. Old cars owned by actors Rajesh Khanna and Hema Malini were used for filming for authenticity. A number of references to real life was also filmed, including a scene in which Om saves Shantipriya from a fire, which was a spoof of Sunil Dutt rescuing Nargis from a fire on the sets of Mother India (1957). For a shot involving a Filmfare Awards ceremony, Khan stood on the red carpet of an actual Filmfare Award ceremony and requested actors to dictate dialogues as she stated. The song "Deewangi Deewangi" was shot over a period of six days. The song "Dhoom Tana" has digitally altered guest appearances, which included Sunil Dutt from Amrapali (1966), Rajesh Khanna from Sachaa Jhutha (1970) and Jeetendra from Jay Vejay (1977). Farah wanted to film Shakira for filming a special appearance had made her commit a few days for the role. Due to the uncertainty of her dates, the idea was scrapped. In February 2007, a filming schedule was completed in Film City. It was then reported that filming would move outdoors after Shah Rukh completed filming for Kaun Bannega Crorepati. In October 2007, Abhishek Bachchan finished filming for his cameo appearance; he shot between 10 and 2 in the night for his screen time of about one and a half minutes. Filming of the last sequence and the end-credit song was done in Film City. Farah continued the tradition of featuring an end-credits song beginning with Main Hoon Na (2004). Om Shanti Om was produced by Shah Rukh's wife Gauri Khan under their Red Chillies Entertainment banner. While Marching Ants handled the publicity design, Gauri was the presenter. Shyam Kaushal, Amar Shetty and Shah Rukh were the action directors. The film's final reel length was 4013.94 ft (1223.45 m).
