Corrected entry: Alex Summers, AKA Havok, is the younger brother of Scott Summers [Cyclops] and is a teenager in the film. Yet in the 90s, when the first X-men was set, Scott was still a teenager when the Cuban missile crisis occurred in 1962, so 30 years between events.

Correction: Scott and Alex are brothers in the comics yes, but it is never explicitly stated that they are supposed to be brothers in the movies. They have the same last name, but no further details are given, therefore, no mistake.

S. Ha

It is stated 2 movies later in X-Men: Apocalypse that Scott and Alex are indeed brothers.

Yes, but they simply decided to make Alex the older brother instead. Changes from the source material aren't considered mistakes, so the original submission is still invalid.
