A new behind-the-scenes video for Avengers: Infinity War has shown Robert Downey Jr. wearing Doctor Strange's Cloak of Levitation. Does this mean Iron Man will end up using magic in the movie? And what does that mean for the Sorcerer Supreme?

One of the biggest sells for Infinity War is the near-endless character team-up possibilities, so it's little surprise the latest featurette pushes that to the fore. However, along with teasing some cool dynamics, it may also give a clearer sense of the plot. Trailers for Avengers 3 have already teased the Guardians, Iron Man, Spider-Man and Doctor Strange working together to launch an attack on Thanos himself, and this video seems to detail more of their plan, with Strange opening a portal for Star-Lord to jump through.

It's important to note that at this point Strange is still wearing both the Eye of Agamotto and the Cloak of Levitation because, in a BTS shot, we can see that cloak on Tony Stark. Is Robert Downey, Jr. just messing around on set, or is this a sign that Iron Man will trade tech for magic? It could actually be the latter; we saw in the full trailer that Tony's Iron Man Prime armor is damaged during the fight with Thanos, so it may be that he's got this as a replacement.

It also serves as a neat potential reference to the current Marvel comics run where Tony Stark has become the Sorcerer Supreme, although given Strange has a long future in the MCU (and Iron Man's days seem numbered) that's probably not what we're seeing here.

A subsequent shot reveals more. At 1:20 in the video, there's another glimpse of Cumberbatch in a scene in which Strange appears to be levitating. However, he's not wearing the Cloak of Levitation (although does still have the Eye of Agamotto). Importantly, this scene seems to correspond with one from the trailers, in which Strange - sans cloak - is tortured by Ebony Maw.

This has potentially revealed quite a lot about Infinity War's plot. It suggests that Thanos's forces will fail to acquire the Time Stone when they attack Earth; the Avengers will then pursue Thanos into space, where they'll team up with the Guardians of the Galaxy. But the attack on Thanos won't go as planned; the Avengers are defeated, and Iron Man's armor is badly damaged. Strange will choose to give Tony the Cloak of Levitation, perhaps in order to escape, but will be captured himself.

Strange's subsequent torture is becoming very curious indeed. It's possible that, while Thanos's agents know Strange possesses an Infinity Stone, they aren't aware it's in the Eye of Agamotto. That would explain why Strange is being tortured; Ebony Maw is trying to learn the Time Stone's location (perhaps even in pursuit of his own agenda).

The Titan sequence remains the most mysterious of Avengers: Infinity War's sprawling story. There are still a lot of unanswered questions - including simply why the Avengers went there in the first place. But this brief behind-the-scenes video may well have given away a lot of the second act's structure.
