The first look on Friday at "Avengers: Infinity War" took fans behind the scenes of the highly anticipated Marvel Studios sequel, and revealed Thanos' new look while also confirming that Earth's Mightiest Heroes will meet the Guardians of the Galaxy. Those are, of course, welcome details, but there may also be clues in the background as to where some scenes of "Infinity War" take place.

At about the 1:38 mark of the video, we see in the background what appear to be storyboards, with a character that looks like Iron Man in flight. At first glance, we might assume he's rocketing through skyscrapers during the Battle of New York depicted in 2012's "The Avengers." However, the landscape looks alien. Additionally, one of the images shows what appears to be Earth, as glimpsed from space.

For more evidence, we need look no further than the interview with stars Robert Downey Jr., Tom Holland and Chris Pratt, who are standing on a decidedly alien-looking set.

Although Thor routinely journeys between Earth and the rest of the Nine Realms, "Infinity War" would mark the first time the Avengers have traveled off-planet on the big screen. It certainly makes sense for the Avengers to venture into the cosmos to battle Thanos and stop his hunt for the Infinity Stones. Perhaps this is how -- and where -- the Avengers cross paths with the Guardians of the Galaxy.

Directed by Joe and Anthony Russo, “Avengers: Infinity War” is scheduled for release on May 4, 2018.
