Thor is a 2011 American superhero film based on the Marvel Comics character of the same name. Produced by Marvel Studios and distributed by Paramount Pictures, it is the fourth film in the Marvel Cinematic Universe (MCU). It was directed by Kenneth Branagh, written by the writing team of Ashley Miller and Zack Stentz along with Don Payne, and stars Chris Hemsworth as the title character alongside Natalie Portman, Tom Hiddleston, Stellan Skarsgård, Colm Feore, Ray Stevenson, Idris Elba, Kat Dennings, Rene Russo, and Anthony Hopkins. After reigniting a dormant war, Thor is banished from Asgard to Earth, stripped of his powers and his hammer Mjölnir. As his brother Loki plots to take the Asgardian throne, Thor must prove himself worthy.
Sam Raimi first developed the concept of a film adaptation based on Thor in 1991, but soon abandoned the project, leaving it in "development hell" for several years. During this time, the rights were picked up by various film studios until Marvel signed Mark Protosevich to develop the project in 2006, and planned to finance and release it through Paramount. Matthew Vaughn was assigned to direct the film for a tentative 2010 release. However, after Vaughn was released from his holding deal in 2008, Branagh was approached and the film's release was rescheduled to 2011. The main characters were cast in 2009, and principal photography took place in California and New Mexico from January to May 2010. The film was converted to 3D in post-production.
Thor premiered in Sydney on April 17, 2011, and was released in the United States on May 6, as part of Phase One of the MCU. The film was a financial success, earning $449.3 million worldwide, and was positively reviewed for its performances but received criticism for some of its plot. Two sequels have been released: Thor: The Dark World (2013) and Thor: Ragnarok (2017). A fourth film, Thor: Love and Thunder, is scheduled to be released in 2022.
In 965 AD, Odin, king of Asgard, wages war against the Frost Giants of Jotunheim and their leader Laufey, to prevent them from conquering the Nine Realms, starting with Earth. The Asgardian warriors defeat the Frost Giants in Tønsberg, Norway, and seize the source of their power, the Casket of Ancient Winters.
In the present, Odin's son Thor prepares to ascend to the throne of Asgard, but is interrupted when Frost Giants, secretly allowed in by his brother Loki, attempt to retrieve the Casket. Against Odin's order, Thor travels to Jotunheim to confront Laufey, accompanied by Loki, childhood friend Sif and the Warriors Three: Volstagg, Fandral, and Hogun. A battle ensues until Odin intervenes to save the Asgardians, destroying the fragile truce between the two races. For Thor's arrogance, Odin strips his son of his godly power and exiles him to Earth as a mortal, accompanied by his hammer Mjölnir, now protected by an enchantment that allows only the worthy to wield it.
Thor lands in New Mexico, where astrophysicist Dr. Jane Foster, her assistant Darcy Lewis, and mentor Dr. Erik Selvig find him. The local populace finds Mjolnir, which S.H.I.E.L.D.agent Phil Coulson soon commandeers before forcibly acquiring Foster's data about the wormhole that delivered Thor to Earth. Thor, having discovered Mjolnir's nearby location, seeks to retrieve it from the facility that S.H.I.E.L.D. has constructed, but he finds himself unable to lift it and is captured. With Selvig's help, he is freed and resigns himself to exile on Earth as he develops a romance with Foster.
Loki discovers that he is Laufey's biological son, adopted by Odin after the war ended. Loki confronts Odin, who wearily falls into the deep "Odinsleep" to recover his strength. Loki takes the throne in Odin's stead and offers Laufey the chance to kill Odin and retrieve the Casket. Sif and the Warriors Three, unhappy with Loki's rule, attempt to return Thor from exile, convincing Heimdall, gatekeeper of the Bifröst—the means of traveling between worlds—to allow them passage to Earth. Aware of their plan, Loki sends the Destroyer, a seemingly indestructible automaton, to pursue them and kill Thor. The warriors find Thor, but the Destroyer attacks and defeats them, prompting Thor to offer himself instead. Struck by the Destroyer and near death, Thor proves himself worthy by his sacrifice to wield Mjölnir. The hammer returns to him, restoring his powers and enabling him to defeat the Destroyer. Kissing Foster goodbye and vowing to return, he leaves with his fellow Asgardians to confront Loki.
In Asgard, Loki betrays and kills Laufey, revealing his true plan to use Laufey's attempt on Odin's life as an excuse to destroy Jotunheim with the Bifröst Bridge, thus proving himself worthy to his adoptive father. Thor arrives and fights Loki before destroying the Bifröst Bridge to stop Loki's plan, stranding himself in Asgard. Odin awakens and prevents the brothers from falling into the abyss created in the wake of the bridge's destruction, but Loki allows himself to fall when Odin rejects his pleas for approval. Thor makes amends with Odin, admitting he is not ready to be king; meanwhile, on Earth, Foster and her team search for a way to open a portal to Asgard.
In a post-credits scene, Selvig is taken to a S.H.I.E.L.D. facility, where Nick Fury opens a briefcase and asks him to study a mysterious cube-shaped object, which Fury says may hold untold power. An invisible Loki prompts Selvig to agree, and he does.
