Dawson Casting: Avoided with Jamal (18-year old Dev Patel playing an 18-year old). Played straight with Latika (Freida Pinto was 25 then).
Director Displacement: This film had two credited directors (Danny Boyle 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.
