History Film / ThorRagnarok

* SealedEvilInACan: Hela has been imprisoned for millennia until Loki inadvertently manages to release her through [[NiceJobBreakingItHero banishing Odin to Earth, weakening him to the point that he willingly gives up on life]]. Odin was the only being powerful enough to keep Hela at bay and his death means that she finally manages to escape her prison.

* CasualDangerDialog: Thor and Loki casually chat with each other while fighting off Sakaarian guards and typing in the stolen security codes.

** The Grandmaster's gladiatorial games are called the ComicBook/ContestOfChampions.

* SpiritualSequel: ComicBook/TheIncredibleHulk and ComicBook/TheMightyThor had previously teamed up in the 1988 MadeForTVMovie ''The Incredible Hulk Returns''.

* SlapstickKnowsNoGender: Valkyrie's intro, where she tries a loose, aggressive swagger down the gangway of her craft while taking a swig but only ends up sailing off the side when she leans too far.

** Sakaaran soldiers dressed like those manning the ''Dark Aster'' in ''Film/GuardiansOfTheGalaxy2014'' can be seen every now and again throughout Sakaar, particularly the second post-credits scene.
** Valkyrie mentions Xandar from ''Film/GuardiansOfTheGalaxy2014'' as one of the planets they could escape to via a portal.

** Thor's gladiatorial helmet uses same collapsing technology as [[Film/GuardiansOfTheGalaxy Star-Lord's mask and Gamora's sword.]]

** While their relationship isn't expressly stated (in the comics they're both Elders of the Universe and consider each other brothers), Goldblum's Grandmaster purposefully evokes [[Film/GuardiansOfTheGalaxy Benicio del Toro's Collector]]. They even have similar hairstyles and facial markings.
** Sakaaran soldiers dressed like those manning the ''Dark Aster'' in ''Film/GuardiansOfTheGalaxy'' can be seen every now and again throughout Sakaar, particularly the second post-credits scene.
** Valkyrie mentions Xandar from ''Film/GuardiansOfTheGalaxy'' as one of the planets they could escape to via a portal.

** When he changes sides, Skurge's WeaponOfChoice is [[ComicBook/LokiAgentOfAsgard machine guns]].

** The BigBad, ComicBook/{{Hela}}, has a black helm with multiple spikes coming out of it, like the comics, in her "powered up" form. Her WeaponOfChoice is similarly a short sword with a spiked blade.

** In ''Film/TheAvengers2012'', Loki tricked Thor with an illusion of himself in the prison cage aboard the Helicarrier, then sneered "Are you ever ''not'' going to fall for that?" While they're escaping from the Grandmaster's world, Loki tries to slip away and leave just an illusion of himself walking beside Thor. This time, Thor doesn't fall for it.

* EvenEvilHasLovedOnes: Granted, exactly how "evil" Loki is is a matter of debate, but he was still the BigBad of ''Film/TheAvengers2012''. Yet he is visibly heartbroken at witnessing [[spoiler:Odin's death]].

* ButNotTooBlack: Averted. The stylist of the movie claims that they considered giving Valkyrie blonde hair, as in the comics. But out of respect of this trope, they left Tessa Thompson's hair black as opposed to making her a DarkSkinnedBlonde.

* ArsonMurderAndJayWalking:

** Creator/MattDamon, Creator/SamNeill and Creator/LukeHemsworth are the actors portraying Loki, Odin and Thor, respectively, in a dramatisation of Loki's life. Ironically, all three were runners-up for the roles in the MCU that they are portraying in the play.

* ClimacticElevatorRide: In the elevator on their way up to steal the Grandmaster's ship, Thor and Loki have a quiet moment to talk. Loki suggests it would be best if he remained behind on Sakaar and Thor wholeheartedly agrees, but [[BreakThemByTalking expresses his regret]] as he had always thought they'd fight side-by-side forever but now realizes that their paths diverged a long time ago. This moment of honest expression clearly touches Loki but undergoes a [[MoodWhiplash tonal shift]] as Thor then suggests they do "Get help" to which Loki declares, "We are ''not'' doing 'Get Help'." The ride ends with a GilliganCut as the elevator's doors open.
-->'''Thor:''' Get Help! Please! My brother, he's dying....

-->'''Loki:''' You had ''one'' job.

* KnifeNut:
** Hela certainly seems to have a fondness for bladed weapons. She can magic knives and swords (not to mention many other weapons) out of thin air and not only fights with them but [[StormOfBlades throws them at her opponents]], impaling people in all directions.
** Loki remains one: he immediately draws knives when freed from Strange's portals and again when he and Valkyrie come to blows.

* LoadsAndLoadsOfCharacters: PlayedWith, as similar to ''Film/AvengersAgeOfUltron'' and ''Film/CaptainAmericaCivilWar'', ''Thor: Ragnarok'' features a sizeable roster of characters, with at least 16 characters.[[note]]Thor himself, Loki, Hulk, Hela, Odin, Valkyrie, Skurge, Heimdall, Doctor Strange, Korg, Volstagg, Fandrall, Hogun, Surtur, Topaz, and the Grandmaster.[[/note]] Granted, this is pretty large for any movie, but to put this into perspective, that is over 4/5 the number of characters of ''Age of Ultron'' (which had 21 main characters), and two less main characters than ''Civil War'' (which had 18).

** While ''Civil War'' was a CrisisCrossover movie that featured LoadsAndLoadsOfCharacters from outside Cap's franchise, ''Ragnarok'' mainly focuses on Thor and his allies from his films ([[ComicBook/TheIncredibleHulk with two]] [[ComicBook/DoctorStrange major exceptions]]). Just for the sake of comparison, while ''Civil War'' features only ''eight'' firmly ''Captain America'' characters[[note]] Cap himself, Bucky/Winter Soldier, Falcon, Sharon Carter, Peggy Carter, Zemo, and Crossbones[[/note]] out of a cast of about '''18''' characters, ''Ragnarok'' only uses about 4-5 non-''Thor'' characters[[note]]Hulk, Doctor Strange, Grandmaster, Topaz, and Korg[[/note]] in a film with about 17 characters.

* GarnishingTheStory: In the opening sequence, Thor briefly fights a fire dragon... just because it [[RuleOfCool looks so cool]].

** At the end, as the protagonists are watching [[spoiler:Asgard being destroyed by Surtur, Korg comments that the as long as the foundations are holding up, they can always rebuild the place. Then the whole planet blows up before their eyes, and Korg meekly concludes, "Now those foundations are gone. Sorry."]]

* HulkSpeak: From the trope namer himself, who, up to this point, had uttered only seven words on screen ("Leave me alone." and "Hulk smash!" in ''Film/{{The Incredible Hulk|2008}}'', along with "Puny god" in ''Film/{{The Avengers|2012}}''). While Hulk is capable of carrying on whole conversations now, he doesn't use pronouns, to the point he even refers to himself in the third person. His sentence structure is simple but he oddly understands concepts like similes and metaphors and has an higher vocabulary than you'd expect as shown in his exchange with Thor:

* InstantlyProvenWrong: Thor promises Banner that he's never gonna have to think about the Hulk again. Cue them running into a street festival celebrating the Hulk.

** After the final battle and [[spoiler:Surtur is laying waste to Asgard]], Korg makes an inspiring speech saying that [[spoiler:as long as the foundations are strong, there's a chance to rebuild Asgard and create a haven for all people and aliens of the universe]]. Immediately, [[spoiler:Asgard explodes to bits]]. Korg cheerfully says, "Now those foundations are gone. Sorry."
