Since the events of the last X-Men film, a degree of progress has been made in the stand-off between mutants and humans: the U.S. government now boasts a full-fledged Department of Mutant Affairs, headed by an un-threatening mutant spokesman with Sno-Cone-blue body fur that puffs out of the sleeves of a cheap suit and the sotto voce intonations of Dr. Frasier Crane. In other words, we have the X-Men to thank for a new bloated, do-nothing government bureaucracy. If you've seen the first two X-Men films, you already know that this show of good will on the part of homo sapiens will go unacknowledged by the series' resident malcontent, Magneto (Ian McKellen) who serves as a kind of Malcolm X-Man for discontented mutants, eschewing any cooperation with the majority in favor of muscle-flexing and, if need be, armed resistance. At around the 45-minute mark in each film, you can count on Magneto to suddenly don a curious-looking rugby helmet and begin using his powers of magnetic attraction to lift automobiles and their bewildered occupants off the ground. This is how he signals that the discussions are over. In this latest outing, Magneto is accompanied, as always, by his trophy mutant Mystique, a beguiling shape-shifter with jaundiced eyes who has the power to double any other person, and usually chooses Rebecca Romijn as a go-to body.
