Warning: Contains potential spoilers for Avengers 4

An eagle-eyed Avengers fan has spotted something rather interesting in an Avengers: Infinity War interview with Robert Downey Jr - like, big spoiler interesting.

Firstly, the behind the scenes interview seems to have been conducted during Avengers 4 as the actor's hair and beard both match up to that time frame, however, the most significant thing is the set.

The Twitter detective wrote: "Just letting you guys know that Tony meeting Shuri and going to Wakanda is basically confirmed from this photo.

"It's his A4 look with the blonde hair and gray beard. Also the background is the same as Shuris in Infinity War."

Now, as we already know, Shuri is awesome and even smarter than the rest of them, so we're guessing any rivalries might have to be put aside to sort out the state of the universe.

Considering Avengers: Infinity War culled the majority of the characters, Tony Stark and the gang could really do with all the help they can get.

Though some of the characters will be returning, not all of them will survive the closing credits of Avengers 4 - if you want to see our theories on who will survive, you can check it out here.

Avengers 4 will be released in the UK on April 26, 2019, and in the US on May 3, 2019.
