Thor - 2011
Three scientists, Jane Foster, Erik Selvig, and Darcy Lewis, are in the New Mexico desert in a four-wheel drive van studying an aurora-borealis-type phenomenon. Suddenly a large tornado/lightning storm develops and they drive towards it. The van hits a man inside the maelstrom and they stop. The man, a well-built blond, is semi-conscious.
A voice-over describes a battle in 900 AD between frost giants and Asgardians; the Asgardians win, take over the power casket, and return to their realm. The speaker is Odin talking to his two sons, one an energetic blond, the other a more thoughtful dark-haired boy. Odin says both of them are worthy but only one can be king.
Years later Asgard is having an elaborate ceremony.
The blond boy is now the adult Thor and he's being formally recognized as crown prince.
His brother Loki looks on enviously. Before Odin can make the proclamation, alarms go off; there are intruders in the secure rooms that hold the frost giant power casket.
A large Destroyer robot kills the intruders and saves the power casket.
Examining the remains, Odin seems unperturbed, yet Thor is angry and wants to attack. Odin says no.
Thor gathers Loki and his close friends, Volstagg, Fandral, Hogun, and Sif, and they ride out to the Bifrost Bridge portal.
The guardian, Heimdall, allows them to pass and the six are transported to the frost giant planet, Jötunheim, a frozen, crumbling wasteland. Suddenly they are confronted by King Laufey, who taunts the Asgardian heroes. More frost giants surround the six and a battle starts. Loki survives with some magic and has an unusual reaction when he is touched by a frost giant. Laufey releases a huge beast and the Asgardians run for their lives. Thor kills the beast but once again the team are surrounded and things look desperate.
Odin arrives to save the day; he apologizes to Laufey for the intrusion and attempts to reinstate peace, but Laufey states that they are beyond diplomacy, that the Frost Giants are now at war with Asgard.
He attempts to stab Odin, who blasts Laufey back and takes the young group home. Back at the Asgard side of the portal, Odin lets the four friends go and confronts Thor and Loki.
Odin is furious that Thor has dragged Asgard back into war, and tells Thor he is not fit to be king.
He strips him of his power, banishes him to Earth and sends his hammer, Mjolnir, after him a few seconds later, saying that whosoever wields the hammer, and is worthy of it, shall have the power of Thor.
Earth: Thor gets a little aggressive and Darcy tases him, knocking him out. The three scientists load him into their van and take him to the hospital. Once again he starts fighting as he wakes up and he's eventually tranquilized.
Erik tries to get Jane to leave him be, saying he is some kind of nut, but she is curious, and attracted to him. They go back to the hospital but Thor has escaped. As they drive off in the van, they hit the Asgardian man again and knock him out but this time they take him with them. Jane gives him civilian clothes that belonged to her ex-boyfriend.
After overhearing locals discussing a satellite crash 50 miles due west, Thor decides to go there and once again Erik tries to get Jane to leave him alone. Thor walks about the town and tries to get a horse in a pet store.
Jane appears and gives him a ride; the two head west in the van.
At the satellite crash site -- actually the place where Thor's hammer came to earth -- a crowd has gathered; people are partying and trying to lift the hammer from the crater. Stan Lee cameos as one of the locals trying to pull the hammer out with his pickup truck.
Government agents from SHIELD take over the site and confiscate Jane's research notes and computers. After dark, Jane and Thor arrive on the scene.
Now the crater is surrounded by guards and tenting.
Thor attacks and Jane huddles in safety.
After beating up many agents, Thor finally reaches the hammer, but is unable to lift it.
He howls at his powerlessness and slumps to the ground, putting up no fight as SHIELD agents close in and take him.
Asgard: Thor's four friends begin to suspect Loki had something to do with Thor's banishment.
Loki realizes he is not a pure Asgardian and Odin admits Loki was taken from Jötunheim as an infant and raised as his own.
