Says the film's casting director Loveleen Tandon, "It was a decision taken by the producers Fox Searchlight, and we had nothing to do with the title of the Hindi version being altered. There was a problem with the branding."
Otherwise everything connected with the international game show Who Wants To Be A Millionaire including the sets and music were copyright-purchased for Slumdog Millionaire.
Infrorms Loveleen, "The first thing that Celadore Films who produced Slumdog did was to acquire the rights for the Who Wants To Be A Millionaire since it's such an integral part of the film."
Speaking on the dubbing Loveleen who has supervised the Hindi dubbing says, "All the actors from the original English including Anil Kapoor, Irrfan Khan and Ankur Vikal dubbed the film.
We got a boy from Chembur Pradeep Motwani to dub for the male lead Dev Patel. I didn't want any exaggerated dubbing. I wanted a young unspoilt voice, hard to find since Mumbai boys become smoking and drinking."
