Loki is back for The Avengers 4!
The diabolical trickster and brother to Thor was spotted on the set of The Avengers 4 in Atlanta, Georgia where a body double for Tom Hiddleston can be seen playing Loki.
Also spotted on set was Chris Hemsworth, back as Thor, and Robert Downey Jr. as Tony Stark and Iron Man.
It's guessed the scene may be some sort of flashback scene (or maybe even time travel?) as the scene features Thor with long hair and Loki wearing the muzzle, which was last seen in the first Avengers movie.
Both Chris Hemsworth and Tom Hiddleston can also be seen in this week's release of Thor: Ragnarok.
The Avengers: Infinity War hits May 4, 2018; The Avengers 4 has a May 3, 2019 release.
As the Avengers and their allies have continued to protect the world from threats too large for any one hero to handle, a new danger has emerged from the cosmic shadows: Thanos. A despot of intergalactic infamy, his goal is to collect all six Infinity Stones, artifacts of unimaginable power, and use them to inflict his twisted will on all of reality. Everything the Avengers have fought for has led up to this moment - the fate of Earth and existence itself has never been more uncertain.
