Trivia

 * Two cinematic versions of Quicksilver currently exist simultaneously. Quicksilver can be used by either Marvel Studios or 20th Century Fox providing that the latter doesn't mention anything about his allegiance to the Avengers and the former doesn't refer to him as a "mutant" or name him as Magneto's son. Marvel Studios President Kevin Feige stated that the Marvel Studios' version of Quicksilver would differ from Evan Peter's version of the character from X-Men: Days of Future Past  in that they would focus on his history in Eastern Europe, while the X-Men version of the character omitted this background detail.
 * Aaron Taylor-Johnson's mid-credits role in Captain America: The Winter Soldier was uncredited.
