* WhatCouldHaveBeen:
** Creator/StevenSpielberg dropped out of the creative team for the opening ceremony of the 2008 Summer Games in protest of China's inaction in the Darfur Civil War. What the ceremony would have looked like in Spielberg's hands is anyone's guess.
** For the 2012 Summer Olympics, various parts of Danny Boyle's opening ceremony were left out due to time restraints from public transportation: stunt bikes [[http://theolympictorch.com/latest/174-danny-boyles-london-2012-opening-extravaganza-to-be-shortened were to be involved]] and a ''Series/DoctorWho'' segment (or at least, music) [[http://www.hypable.com/2012/07/28/doctor-who-cut-from-olympic-opening-to-save-time/ was cut]].
