X-Men Origins (2009)

James Logan aka Wolverine and his brother Victor Creed (who will later become Sabretooth) run away together as children in the mid 1850's after Logan kills their biological father who had murdered Logan's adoptive father. After serving together in many wars they are recruited by William Stryker to serve in a special unit made up of mutants. After wiping out an African villiage, Logan quits the unit and goes off to live a life of peace in the Canadian Rockies with his girlfriend later to be known as the Silver Fox.

Six years pass for the both of them until Stryker shows up and asks Logan to come back and be a part of a new Weapon X project. Logan refuses but Creed shows up and murders Logan's girlfriend leaving him wanting revenge against his brother. Logan accepts Strykers offer to be infused with Adamantium so that he can be indestructable and go after his revenge but is double crossed by Stryker and hears him give the order to wipe his memories. Escaping before this can happen, he goes searching for Creed killing anyone who gets in his way.

After reuniting with a few members of his old team, he finds out that Stryker and Creed are actually working together to kidnap mutants and keep them in confinement working on a new project, Weapon XI and that only one person knows where their new base of operations is. Remy LeBeau aka Gambit is the only mutant to escape this place and Logan along with John Wraith go searching for him in New Orleans. They find him in a card game where Logan tries to question him but with less than desireable results. After being blasted through a wall by Gambit, Logan sees Creed standing over the dead body of Wraith and the fight is on. Right when Logan is about to get his revenge and kill Creed, Gambit comes flying in with his staff and blows everyone apart. Creed uses this distraction to escape while Logan and Gambit go at it. After showing Gambit the light (with his claws), Gambit agrees to take Logan to Three Mile Island where the facility is hidden.

Arriving at Three Mile Island by plane, Logan finds many mutant children kept prisoner by Stryker and Creed with the support of the U.S. Government. Logan confronts Stryker while he is at the finishing point of his Weapon XI project and learns the truth that Silver Fox isn't dead but was keeping and eye on him those six years and manipulating him with her mutant power of persuasion. After leaving, Fox confronts Stryker demanding the release of her sister only to be placated and told to wait. Creed comes in and Fox tries to persuade him that Stryker is only using them. Only this doesn't work and she is almost killed by Creed. Logan hears her screams and comes to her rescue almost killing Creed but being convinced by Fox that if he does that then they will be no better then Stryker. She also convinces him that she truly loves him.

Fox and Logan then go to free the children. Fox leads them out of the facility while Logan goes in search of Stryker. In a firefight, Fox is wounded and sends the children on while she goes back to look for Logan. The children make it out of the facility and are met by none other than Charles Xavier who offers them a ride in his helicopter and protection at his school.

While Logan is searching, Stryker activates Weapon XI who is a combination of all the mutants abilities with none of their weaknesses. XI and Logan's fight ranges from the inside to the outer top of a nuclear reactor and it appears Logan is outmatched until Creed shows up to help save him using the line; "No one is allowed to kill you except me..." Back to back they take on XI together until Creed grabs him by the neck, stabs him in the chest and Logan decapitates him with those claws. XI's head and body go falling into the reactor cutting chunks out of it the whole way down. Logan tells Creed that this changes nothing and they go their seperate ways.

After getting to the ground, Logan is saved from the falling debris of the reactor by Gambit. They then go their seperate ways in search for Stryker but Logan comes upon the wounded body of Fox and starts carrying her toward the plane. Stryker intercepts them and shoots Logan in the head with Adamantium bullets which are the only thing that can really "hurt" him. This knocks him out long enough for him to go after Silver Fox but she turns the tables by touching his ankle and telling him to "walk until you bleed... Then keep walking."

Gambit comes back finding Logan regaining consciousness but without any memories. Finding the body of Silver Fox, Gambit asks if Logan knows her but he doesn't. Going their seperate ways, the movie ends here but you should watch through the credits all the way. Stryker is picked up by the MP's with bloody feet for the murder of a general and Logan is last seen in an Asian bar drinking shots and trying to remember who he is.
