There are 4 movies in the X-Men film series. This is a list of them: X-Men, X-Men 2: X-Men United, X-Men 3:The Last Stand, and X-Men Origins: Wolverine. The prequel, X-Men: First Class is scheduled to come out in theaters on June 3, 2011. Also, numerous spin offs have been planned, one of wich is a "one-off ", The Wolverine. Others are Deadpool and New Mutants. X-Men 4 is also in planned. There are many planned movies with no planned cast including Gambit, Emma Frost, Juggernaut, Storm, Mystique, Cable, Dazzler, and Longshot. I don't know if the last three movies i mentioned have anything to do with this film series, but most likely they will. The X-Men film series is Marvels second most successful film series behind the Spider-man film series.
