* ActorAllusion: Chitti waxing poetic over Sana may come out of leftfield for some, but it ''is'' the sort of thing you'd get, at any point in history, with anyone that could be labeled WorldsMostBeautifulWoman.
** In the Japanese dub, Creator/DaisukeOno as Chitti is this if you take into account he previously voiced a robot [[VideoGame/TatsunokoVsCapcom before]]
* DawsonCasting: Rajnikanth (who was 60 when the movie came out!) as Vaseegaran, deliberately averting MayDecemberRomance.
* PlayingAgainstType: Evil!Chitti is notably Rajnikanth's first villainous role ''after thirty years''.
* WhatCouldHaveBeen: According to [[http://www.awn.com/articles/article/powering-bollywoods-sci-fi-sensation/page/2%2C1 this article on VFXWorld]], [[Creator/IndustrialLightAndMagic ILM]], Creator/TippettStudio, Creator/CafeFX and Creator/ZoicStudios were among the visual effects studios initially involved on the project. Then the original production company closed down, forcing the CG to be done in UsefulNotes/{{India}} and UsefulNotes/HongKong.
