Thankfully, it did not take the end of the world as we know it for Tony Stark (Robert Downey Jr.) and Pepper Potts (Gwyneth Paltrow) to patch things up. Though the duo may have been "taking a break" during Captain America: Civil War, by the time she cameoed in Spider-Man: Homecoming, Pepper and Tony were very much on again, a storyline that will continue into Avengers: Infinity War.

"He and Pepper have clearly resolved their differences," Downey Jr. explained on the set of Infinity War of how the couple rekindled their romance. "The way you resolve those differences is you shack up together long-term."

Iron Man will, naturally, play a large part in the newest Avengers installment, but when, where and how Pepper factors in remains to be seen, the aforementioned living situation aside. "Robert and I definitely work very well together," Paltrow said. "But I don't think you can construct that chemistry. It's something that is there or it's not."

Infinity War will also see Tony Stark reunite with his estranged Avengers brethren, as well as Peter Quill (Chris Pratt) and the Guardians of the Galaxy. "This is D-day, man. People don't understand what they're walking into with this movie," Pratt teased.

"This is a giant spectacle," he added. And there may be even more appearances by characters we don't know about yet, with Pratt promising the movie "has cameos from every major character that's existed in the Marvel Cinematic Universe for this epic, two-part battle."

The entirety of the Marvel universe is coming together to take on one intergalactic foe: Thanos the Mad Titan, played by Josh Brolin. Infinity War follows Thanos as he attempts to collect all six Infinity Stones to wipe out half the universe. Or as Brolin put it, "He's going for all power."

Prior to Infinity War, out April 27, the last Avenger to cross Thanos' path was Thor, with a stolen Stone stowed aboard the Asgardian's Earth-bound ship, and Chris Hemsworth cautions, "His sheer force and strength is something that none of the Avengers or anyone in the MC Universe has ever really encountered before."
