Even superheroes need lunch. On Wednesday, Robert Downey Jr. shared a photo of himself and a few “Avengers: Infinity War” stars sitting down to eat. The actors were all in costume while chowing down.

The photo, most likely taken on the Atlanta “Infinity War” set, shows Downey in an Iron Man shirt, as evidenced by the hole in his top. Expect a light from Tony Stark’s arc reactor to be there when the movie hits theaters. “Doctor Strange” stars Benedict Cumberbatch and Benedict Wong are both in their characters’ robes. It isn’t clear if Ruffalo was in costume as Bruce Banner or not (to be fair, they dress pretty similarly).

“Forks, tongs, cans + bottles + a Wong... Help us,” Downey wrote, referring to their lunch spread. Downey also used a host of hashtags to refer to the group. He dubbed Stark and Strange “#beardbros,” which is only fitting when you see how similar their facial hair is. Stark and Banner have often been referred to as “#sciencebros,” and Downey probably isn’t the first person to call Cumberbatch and Wong “#benedictsquared.”

The fact that all four are on set together means they’re definitely in a scene together, but that isn’t too surprising. Tony and Bruce have long been the characters on the science side of the team, so it makes sense that they’d include Strange, a renowned surgeon and a sorcerer.

This is just the beginning of exciting images, though. As “Avengers: Infinity War” gets closer to being released, fans are sure to see more of their favorite characters from the Marvel Cinematic Universe (MCU) meet. Even Scarlett Johansson recently said she was astounded by just how many superheroes could fit into one scene.

“I think in one particular scene there’s like 32 of us,” Johansson estimated on “The Late Show with Stephen Colbert” last week. “There’s a lot. There are so many of us. I don’t know who’s a Marvel character and who’s like a crew member, honestly.”

The characters aren’t gathering for just any old villain. Thanos (Josh Brolin) is coming. The purple alien is searching for the Infinity Stones. Once he has them all, he’ll be have the power to destroy the universe.

A threat to the whole universe will unite the MCU. The cast includes Captain America (Chris Evans), Black Widow (Scarlett Johansson), Scarlet Witch (Elizabeth Olsen), Vision (Paul Bettany), Winter Soldier (Sebastian Stan) and more Avengers. Gamora (Zoe Saldana), Nebula (Karen Gillan), Star-Lord (Chris Pratt) and the other Guardians of the Galaxy will also appear. Black Panther (Chadwick Boseman) and Spider-Man (Tom Holland) will swing by as well. It’s also rumored that Captain Marvel (Brie Larson) will be introduced in the epic Marvel movie, but that hasn’t been confirmed yet.

“Avengers: Infinity War” hits theaters May 4, 2018. Anthony and Joe Russo, who directed “Captain America: The Winter Soldier” and “Captain America: Civil War,” will direct the flick.
