"So I was in New Orleans and I was in Green Lantern, but I was barely doing anything. I’d be in my hotel room and it’d be like 1 AM, and the infomercial for the Shake Weight came on. I was like, 'Screw it! I guess I’m buying everything I see on TV tonight – I’m gonna buy knives and some sewing thing.' I bought exercise DVDs, too, but the one thing I bought that I kept was that Shake Weight… and then I had it shipped to Australia and I put it in the movie!"

37. The Hemsworth Brother Cameo

Marvel fans hoping to find out just how much damage had been done to Asgard under Loki's (disguised) rule got their answer soon in Ragnarok, thankfully showing Thor's brother was a king of neglect, if anything. Instead of keeping a watch on galactic threats, or realizing what kind of power it takes to keep the Asgardian monsters at bay, he enjoyed luxuries and the flattery of theater. Specifically, a dramatic recreation of his own 'death' - at least in the minds of everyone in Asgard - in the last Thor movie, The Dark World. And famous as he may be for deception, Loki clearly appreciates the emotion and heartbreak visible in the performance of Thor's on-stage stand-in.

It isn't just any actor doing their best impression of Chris Hemsworth's god of thunder, though. It's his older brother Luke Hemsworth, long known by primarily Australian audiences before appearing as the head of security in HBO's Westworld. We'll let fans decide if the 'Actor Thor' lives up to the standard set by the real thing, and assume Chris kept his other brother away since Liam Hemsworth's run at the Thor role almost netted him the part in the first place.

36. Matt Damon Won't Turn Down Work

The fact that the version of Thor being fictionally played in a fictional film is another Hemsworth is an amazing twist, but is obviously not the cameo that will get the most people talking. That honor falls to Matt Damon, making the trip from Earth all the way to Asgard to land the (presumably) starring role of Loki Laufeyson. Which means Ragnarok and Christopher Nolan's Interstellar are probably now tied with EuroTrip for the most unexpected appearance of the Good Will Hunting star. Fine company.

The real question for fans is whether the actor seen portraying the uncredited role of 'Actor Loki' is a resident of Asgard who bears a striking resemblance to Matt Damon... or actually IS Matt Damon. Loki's powers of deception and illusion mean it's possible that Matt Damon of Marvel's Earth was snatched up and brainwashed. That's the version of the story we're holding as canon.

35. Sam Neill's Odin

The theories were spinning from the moment it was confirmed actor Sam Neill had a role in Ragnarok, expecting such an esteemed actor to hold a significant place in the MCU. While a little disappointing to fans that no role as an Eternal, or even a cosmic figure of authority rests in the Jurassic Park star's future, the cameo is a special one. Late to the play, his sizable beard means that some in the audience might not actually recognize Neill as the theatrical version of Odin Allfather. But Loki has obviously turned to the very best to capture his father's personality and sense of ceremony (better than Loki actually can, as quickly becomes clear).

The beard Neill's sporting is surprisingly a step back from the bushy face-sweater he wore in Hunt For The Wilderpeople, the previous movie from Ragnarok director Taika Waititi. Neill was obviously called on at least in part because of this recent collaboration, resulting in a Jurassic Park reunion of Neill and Jeff Goldblum (even if they never get to share a scene).

34. Murder By Mjolnir Returning?

At this point audiences have seen Thor kill dozens, if not hundreds of enemies living, dead, or artificial thanks to the Hammer called Mjolnir that he swings, throws, flies with, and fires lightning through. But Thor: Ragnarok actually finds a new way to make Mjolnir murderous, relying on the god of thunder's ability to call it to his palm no matter where in space it - or he - may be. Throwing Mjolnir into the distance and placing his hand on the back of Loki's head (whilst masquerading as Odin), Thor threatens his brother with the truth: that no power or object in creation can stop Mjolnir from returning its impossible density and weight to Thor's palm. Since Loki's head stands between the two... you get the idea.

It's a deviously clever intimidation tactic by Thor, just as it was when it appeared in Issue #359 during the legendary Walt Simonson's Thor run. In that version of the story it was a far more romantic squabble in which Thor and Loki were engaged, but the process was the same. Another Easter Egg for the diehard Marvel fans to enjoy - and a plan that worked like a charm in both cases.

33. Shady Acres Callback

The finished cut of the film may have removed the New York City scenes from Ragnarok, but some evidence of Thor and Loki's trip remains. What was removed was the pair being reunited with their father, shown as a vagrant. What remained was the pair being intercepted by Marvel's Sorcerer Supreme, Doctor Strange himself. But not before Loki led Thor to the exact place that he had left his father when exiling him from Asgard to Earth. Unfortunately, all that remains is... the remains of the senior living facility where Odin was delivered - Shady Acres.

That name is a bit of a running joke in Hollywood, after it appeared as a special care facility in Ace Ventura: Pet Detective (1994). In that movie, it was a play on the director's name: Tom Shadyac. In the years since, countless production designers have clearly agreed that 'Shady Acres' is a pretty good name for a retirement home, senior living center, or any variation thereof.

32. Mjolnir in Disguise

Some will immediately question Thor's reason for bringing an umbrella on his and Loki's trip to Earth, and others may not notice the telltale hum it emits. Doctor Strange sees through the illusion, though, seeming to recognize that Mjolnir has been given the same bit of civilian 'cloaking' as Thor and Loki. Transforming Mjolnir into an umbrella is a wise move, but it's also a terrific throwback to the original comics, when Thor carried on a life on Earth as Dr. Donald Blake. The first Thor made the first connection to the comic character, alluding to Jane Foster's ex of the same name, later used as cover for Thor's civilian identity.

The reason Ragnarok sures that bit of fan service? In the comics, Donald Blake carried Mjolnir around disguised as a cane. When trouble struck and demanded the emergence of the god of thunder in all his glory, he would tap the cane forcefully to the ground and be revealed in a magical burst. When Thor and Loki are ambushed by Hela, the hero follows suit, slamming down the umbrella and dispelling the illusion in a blast of lightning.

31. Hela Turns Tables on Loki

All things considered, Thor and Loki take the surprising news that they've got an unknown, secret, imprisoned, murderous sister quite well. It's a good thing, too, since she shows up to try to kill them not long after. But not without first giving them the chance to show their loyalty to her power, arriving with a simple demand: "Kneel." Thor takes time to weigh the situation as it's developing... Loki, on the other hand, already knows whether or not he's capable of taking a knee to a sister he just met. But his exasperated response is also playing on his own introduction style, circa The Avengers.

For those who may not recall, Loki made the exact same demand when first revealing himself to the people of Earth in . There wasn't an opponent powerful or proud enough to give the same indignant response then, but Loki reacts exactly as one would expect. Definitely a more subtle callback than his joy at seeing Thor take a Hulk-pumelling, but just as good.
