The first X-Men film has turned 20 and cast members Ian McKellen, Hugh Jackman, Halle Berry and Famke Janssen marked the milestone year of the release of the mutant movie on social media.
Based on the characters created by Stan Lee and Jack Kirby in Marvel Comics, X-Men, directed by Bryan Singer, was released in 2000, and its success led to a series of sequels, prequels, and spin-offs, with the popularity of the series seeing a re-emergence of the superhero genre.

McKellen, who played Magneto in the films, shared a picture on Twitter where he could be seen making a call from a "working phone booth" with the date of the film's release visible on a large hoarding. "It was twenty years ago today, when there was still a working phone booth on Santa Monica Blvd and La Brea," he captioned it.
