- At first glance, Mystique's scales might just seem like a simple design choice added to make her more distinctive on screen, but they're quite thematically fitting as well. Think about it: she has scaled skin and yellow eyes, she doesn't appear to have nipples, and she even seems to shed her skin whenever she changes form; she seems to be part-reptile, with her design evoking a chameleon, an animal famous for changing its color as camouflage.
- The final shot in the film is of Magneto in his cell, and Xavier moving away from him. This calls back to their first scene together, where Magneto walks away from him.
- Rule of Symbolism here: the two have their backs to each other, representing their opposing views. While Magneto is enclosed in a cell, Xavier is moving forward, representing their own beliefs of cooperation as a dead end and an open route. (Magneto is also trapped in his own cynicism and prejudice, while the open Xavier is able to make progress)
- The movie is essentially a loose adaptation of "Days of Future Past" that reverses the roles of the X-Men and the Brotherhood. In both versions, Senator Robert Kelly tries to get the Mutant Registration Act passed through Congress, the Brotherhood targets him in retaliation, the X-Men jump in to save him, and one side is motivated by horrific memories of living in a concentration camp. The difference? In the movie, Magneto is the one haunted by memories of concentration camp life. In the comics, it's the X-Men.
In the movie, Magneto suffered horribly in Auschwitz, so he and the Brotherhood kidnap Senator Kelly, fearing that his actions will lead mutants to a similar fate. In the comics, the X-Men suffer horribly in a Sentinel-run concentration camp in the future, so they go back in time to save Kelly from the Brotherhood, hoping that this will stop the years of conflict that created their Bad Future in the first place. The X-Men and their nemesis suffer the same fate, but take completely opposite actions in response.
- Magneto's disgusted remark of "You homo sapiens and your guns" makes all the more sense if you remember how his mother died and Charles lost the use of his legs in X-Men: First Class.
- Magneto's description of God sounds a lot like Professor X, and the connection becomes more obvious after it's revealed in X2: X-Men United that Magneto views mutants to be gods among insects, and there is no one in the world he respects (and loves, as we learn in X-Men: First Class) more than his old friend.Magneto: I've always thought of God as a teacher, a bringer of light, wisdom, and understanding.
