It’s unknown where the image originated, but if legit, it appears to be from the editing room of The Avengers: Infinity War, which recently finished filming.
Taking a closer look at the image, it almost appears as if Doctor Strange is phasing through something, almost as if he perhaps in some incorporeal form or astral projection, with Spider-Man looking and shown in his new Avengers costume, which the D23 Infinity War footage confirmed will be in the movie.
The Avengers: Infinity War hits May 4, 2018 directed by Joe and Anthony Russo also starring Robert Downey Jr. as Iron Man, Tom Holland as Spider-Man, Chris Pratt as Star-Lord, Benedict Cumberbatch as Doctor Strange and Josh Brolin as Thanos.
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.
