Thor: Tales of Asgard (2011) is a Direct-to-Video animated film from Marvel Animation and Lionsgate featuring the adventures of a teenage Thor, his little brother Loki, and the Warriors Three as they try to retrieve the lost Sword of Surtur from Jotunheim. Long story short: nothing goes as planned.In the end, what starts out as a harmless adventure quickly turns deadly, and Thor must now prove himself worthy of the destiny he covets by saving Asgard itself.
The Thor: Tales of Asgard movie provides examples of the following tropes:
Adaptation Dye-Job: Small one, but Loki's hair in both the comic and movie is clearly a jet-black. It's not clear why it was changed to brown, but possibly it was due to the problems of shading and giving depth to entirely black hair in animation. Who's to say it won't eventually turn black, after what happened in the end?
Adorkable: Little Loki getting soaked by his "water snake" starts out so cute.
An Ice Person: The Frost Giants. Loki also, given his Frost Giant heritage.
Almost Kiss: Thor interrupts one between Loki and Amora.
Big Brother Instinct: Thor towards Loki, though Loki, being the smarter brother, also looks after Thor in his own way.
Bittersweet Ending: By the end Thor and Odin reconcile their family differences, but several Frost Giants have died, Asgard and the Valkyries have been attacked, and Loki had to kill a former family friend.
Blatant Lies: Loki: (after Thor loses his sword in a public training match) "You were victorious despite the trouble with your sword's grip... Plainly it was too slick. I'll reprimand the dwarfs."
Continuity Nod: Loki hands Thor a wooden hammer during the bar fight and it proves far more useful than his sword.
Also, Loki's Frost Giant heritage is hinted at when he handles the cold of a snowy Jotunheim better than his bundled and burly companions.
When Thor is preparing for his journey he stands in a armory with Mjolnir and the Axe of the Excecutioner on display.
Cool Down Hug: Thor gives Loki one after he uses the sword to kill Algrim.
Cry Cute: Loki cries when he finds Odin gravely injured in battle with Algrim.
Evil Former Friend: Algrim. Thor won't forgive him for betraying the House of Odin, but can't forget their years-long friendship.
Evil Weapon: Word Of God confirms the Sword of Surtur can influence its wielder. It influences Algrim into attacking Asgard and is essentially doing all of the fighting during the battle against Odin such as seeing through Odin's illusions.
Fanservice: The scene where Thor spies on the Valkyries and finds them all bathing naked in the springs. Cut to Sif in a robe with clearly nothing underneath, which is barely staying together.
Fantastic Racism: Between the Asgardians, Frost Giants and Dark Elves to varying degrees.
Foreshadowing: Loki's control over water (and ice and mist by extension), as well as his immunity to the cold in Jotenheim hints at his Frost Giant heritage.
Also, the ending, with Loki murdering Algrim in cold blood and then hiding in his temple to play with his (growing) magic, hints at his future Face-Heel Turn.
Getting Crap Past the Radar: Tons of it. From Amora whispering seductively in Loki's ear (which triggers an obviously turned on expression on his face) to Sif shooting an arrow into the archery dummy's crotch to Fandral being asked how many of the Valkyries he's 'angered'.
Tragic Villain: Algrim. Given the fact that his family and whole people were slaughtered thanks in part to Odin it's no wonder he's pissed. Yes working with Surtur was stupid but again people can be stupid when desperate.
