Thor: The Dark World
Agents of S.H.I.E.L.D.
- "I will die a warrior's death! Stories will be told of this day!"
Sif is the goddess of war and the friend of Thor. Thanks to Thor, who believed in her capabilities, she became one of the most apreciated warriors of Asgard, along with the Warriors Three and the Thunder God himself.
Along with Loki and the Warriors Three, Sif is convinced by Thor to attack Jotunheim, in response of an attempt by some Frost Giants to steal the Casket of Ancient Winters. While in Jotunheim, Sif fights alongside with her friends against an army of Giants led by Laufey himself, and manages to slain many of them, but is forced to flee when they're outnumbered. Eventually, the team is saved by Odin, who intervenes to prevent their killing. Helpless, Sif assists to Thor's banishment on Earth.
Some days later, Sif persuades the Warriors Three to ask Odin to recall Thor back home, but when they arrive in the throne room, they find Loki sitting as the new ruler of Asgard, as a substitute to Odin who's fallen into Odinsleep. Loki denies their request to call his stepbrother back, but they decide to ignore his order and to go to Midgard anyway. Heimdall agrees with them and opens Bifrost Bridge for them, and the four gods arrive on Earth, in New Mexico. Here, they easily spot Thor, and find out that he's been tricked by Loki's lies. Briefly later, The Destroyer is sent to Earth by Loki to kill Thor and the other Asgardians, and Sif engages it in battle with her friends. While the Warriors Three buy her some time, Sif climbs a rooftop and attacks the Destroyer from above, piercing its throat with her spear. Immediately after, the Destroyer regenerates itself and almost vaporizes her with his energy blast. Sif flees with her companions, leaving Thor, who claims to have a plan, behind, but only to assist his sacrifice and his rebirth in his divine form. Back in Asgard, Sif brings Heimdall to the Restore Room, while Thor fights, and eventually defeats, Loki.
Along with other Asgardians, Sif celebrates Odin's return to the throne and Thor's return in the realm, participating to a gargantuan banquet.
After Odin used dark energy to send Thor to Earth to retrieve Loki and the Tesseract, Sif informed Heimdall that the Allfather was weak but under Eir's care. She then asked about Thor and Heimdall informed her that Thor survived the journey.
Sif was present when Thor returned to Asgard with Loki and the Tesseract. She was also present when Thor rallied his fellow Asgardians, informing them that they were to protect the Nine Realms from the Marauders.
- "I had things under control!"
After the Battle of New York, Sif was battling in Vanaheim when Thor arrived, despite her claims she was in control. After Thor quelled the events, Sif had noticed Thor had become distracted as of late. It was shown Sif has feelings for Thor, but he was unable to reciprocate them because his heart belonged to Jane Foster. When Jane arrived on Asgard, Sif glared at her, clearly jealous of her, but none the less helped Thor escape with her to the Dark World with Loki. She was presumably charged with treason because of her involvement, but released due to Thor's action on Earth. After the conflict Sid and Volstagg gave the Aether to the Collector.
- "Your world is in grave danger!"
Sif arrived on Earth, tracking to capture the Sorceress Lorelei, who had escaped during the Dark Elf invasion of Asgard. She was greeted by S.H.I.E.L.D. agents, but was shocked by the fact that Agent Coulson had returned from the dead. Sif explained Lorelei's powers over men and that a magical collar is key to stop her. After tracking her to a local biker gang, she assisted Agents Coulson and Ward in fighting her brainwashed minions, but failed to stop her escaping with Agent Ward. With the collar damaged, Sif and Melinda May had a heart to heart about Lorelei's history with Sif as well as how Lorelei finds a special thrill in enslaving men that are already taken, such as Agent Ward was with May at the time. When Ward and Lorelei took the SHIELD's flying base, Sif was locked in the interrogation room and blown out of an airlock, however thanks to intervention by Skye, she managed to get back inside to confront Lorelei. In a vicious swordfight between the two, Sif got the upperhand and managed to get the repaired collar around her neck. She escorted Lorelei back to Asgard and said her farewells to the S.H.I.E.L.D. agents.
Heimdall detected the arrival of a Kree on Earth, so Odin sent Sif back to Earth to apprehend this newcomer. Sif tracked down her quarry to Faro, Portugal, and engaged him in broad daylight on a crowded pier. Though she managed to damage the Kree's device that allowed him to masquerade as human, Vin-Tak hit her with his truncheon, which erased all memory of her identity and mission, and tossed her into the sea. By the time she made it back to shore, it was nightfall and all she could recall was the word "Kava". She soon came to the attention of S.H.I.E.L.D., and after they reconstructed her last movements and the identity of her quarry, she realized that "Kava" was the Kree word for "keys". This revelation enabled S.H.I.E.L.D. to narrow down the Portuguese city called "Chaves" translating into "keys", where they captured Vin-Tak.
Vin-Tak insisted he was not a threat, and upon their return to the Playground he used his truncheon to restore Sif's memories. Vin-Tak then revealed that he was on Earth due to a Diviner being used. They soon determined that Skye was an Inhuman when she caused a seismic disturbance. S.H.I.E.L.D. moved to protect Skye as Sif pursued her, insisting that she must be taken back to Asgard for protection. However, Skye shot herself with an I.C.E.R. to stop the tremors.
The next day, Sif took a brainwashed Vin-Tak who has his mind wiped back to Asgard so he could be sent home. Before they left, Sif asked Coulson if he was sure he wanted to keep Skye on Earth due her dangerous power, he said he did.
Being the only female warrior in Asgard, Sif is very proud and always eager to prove herself. She's the closest of friend with Thor and the Warriors Three, and she's an honorable warrior on the battlefield. She often is independent and uneasy in following orders. Sif is the first person to suspect Loki of treason following Thor's banishment, showing that she is very observant.

Behind the scenes
- Jaimie Alexander had to exercise for hours in a gym daily in order to be prepared for the role, although this kind of preparation wasn't new to her, as she had been in her high school's wrestling team.
- Alexander was injured on the set of Thor: The Dark World in September 2012. About the injury, she said "It was raining, it was dark outside, it was like 5 in the morning - and I went down a metal staircase and slipped and slipped a disc in my thoracic spine and chipped 11 of my vertebrae. I knocked my left shoulder out of place and tore my rhomboid on my right side... It took me out of filming for a month".
- In the comics, Sif is Thor's lover and main love interest, not just a friend or a teammate. Her feelings for Thor are hinted in the end of the movie when she looks at him talking with his father. Heimdall and Sif are also brother and sister, though this was not explored in the film.
