* ActorAllusion: Prem says that he is a former winner. His actor Anil Kapoor was a guest on the real show and won 5 million Rupees.
* ColbertBump: Averted. The global popularity of ''Series/WhoWantsToBeAMillionaire'' was largely unaffected by the show's role in the movie.
* DawsonCasting: Avoided with Jamal (18-year old Dev Patel playing an 18-year old). Played straight with Latika (Freida Pinto was 25 then).
* DirectorDisplacement: This film had two credited directors (Creator/DannyBoyle and Loveleen Tandan) but Boyle got all the credit. Reportedly, Tandan directed much of the flashback sequences with Boyle while all of the present day scenes were done by Boyle himself. This because of the Director's Guild's rules. Tandan also was a casting director on the film.
* DirectToVideo: ''Almost,'' until Fox Searchlight signed on to be the distributor.
* FakeNationality: Ethnically Indian Brit Dev Patel as Jamal.
* HeyItsThatGuy: [[Series/{{Skins}} Anwar]] sure has come a long way.
** And the host of ''Series/WhoWantsToBeAMillionaire'' is played by Creator/{{Anil|Kapoor}} '''[[Creator/AnilKapoor freaking]]''' [[Creator/AnilKapoor Kapoor]].
** And then there's [[Film/TheNamesake Gogol's dad]].
* LifeImitatesArt: Actors Dev Patel (Jamal) and Freida Pinto (Latika) are now a real-life couple.
* PlayingAgainstType: Hard to believe but Jamal is this for Dev Patel. His time in ''{{Series/Skins}}'' and roles in the two ''Film/TheBestExoticMarigoldHotel'' films have him playing campy LargeHam characters.
* RomanceOnTheSet: Dev Patel and Freida Pinto became a couple while filming ''Slumdog Millionaire''. Pinto was engaged to someone else at the time, but broke it off.
* WhatCouldHaveBeen:
** Danny Boyle desperately wanted Shah Rukh Khan - who had hosted the final season of ''Who Wants To Be A Millionaire?'' - to play the host. However he wasn't available.
** "Jai Ho" was written for another film, but its producer couldn't find a way to fit it in, so it was allowed to be used here.
