The "Trinity" that started it all in "Iron Man" will return 10 years later for the next "Avengers" movie (and maybe the one after that, too).

Robert Downey Jr. (Tony Stark/Iron Man), Gwyneth Paltrow (Pepper Potts), and Jon Favreau (Happy Hogan) got this whole Marvel Cinematic Universe party started in 2008, and both Downey and Favreau shared the same adorkable photo of the "Infinity Trinity" in Atlanta for "Avengers: Infinity War," which opens in 2018:

Infinity Trinity ... #infinitywar ????and street cred @jimmy_rich represent @marvelstudios and @therealstanlee ...

Look at that goofball. "Avengers 3," titled "Avengers: Infinity War," has already finished filming, so why share that photo now? "Avengers 4" is now filming in Atlanta, so either this is for "Avengers 4" and they're just calling it "Infinity War" (Marvel originally called the two movies Infinity War Part 1 and Part 2) or this is a throwback to "Infinity War" filming. Even if it's a throwback to earlier this year, they could still all be in "Avengers 4" together. We wouldn't mind.

Downey and Favreau both had sizable roles opposite Tom Holland in "Spider-Man: Homecoming," and (SPOILER ALERT) the ending also featured a cameo from Paltrow in the long-awaited return of Tony's better half. Will Tony and Pepper be engaged in "Infinity War"? Will there even be time for that kind of lightness with the universe at stake, and so many dozens of characters to navigate?

"Avengers: Infinity War" opens May 4th, 2018. "Avengers 4" is now filming for its May 3, 2019 release.
