Benedict Cumberbatch, Robert Downey Jr. Bond Over Facial Hair and La Croix In 'Avengers: Infinity War' Set Photo
More of the Hottest Male Superheroes

Meet the #BeardBros.

Robert Downey Jr. shared a photo from the set of "Avengers: Infinity War" on Wednesday, showing him, Benedict Cumberbatch, Mark Ruffalo and Benedict Wong bonding at craft services.

This is the first time we've seen Cumberbatch and Wong -- who both starred in "Doctor Strange" -- interact with the two Avengers. The pic also gives fans a look at Benedict's new costume.

"Forks, tongs, cans + bottles + a Wong... Help us," Downey Jr. captioned the photo, along with a string of hashtags including: #healthenet #afeastoffriends #Avengers #AvengersInfinityWar #universescollide #sciencebros #facialhairbros #beardbros #holmies #benedictsquared #avengersassemble #marvel #mcu #ironman #drstrange #hulk #benedictcumberbatch #benedictwong #lacroix

The hashtags point out Strange and Tony Stark's similar facial hair, as well as the fact that both actors have played Sherlock Holmes; one on film and the other on BBC.

"Infinity War" is going to be one packed film when it comes to Marvel characters. "I think at one point, 61 or 62 Marvel characters in it," Scarlett Johnansson told Stephen Colbert earlier this month. "Yeah, there's a lot ... I think in one particular scene there's like 32 of us. There's a lot."

In addition to the stars above, Chris Hemsworth, Chris Evans, Jeremy Renner, Paul Bettany, Elizabeth Olsen, Don Cheadle, Josh Brolin, Samuel L. Jackson, Chris Pratt, Zoe Saldana, Dave Bautista, Karen Gillan, Bradley Cooper, Vin Diesel, Chadwick Boseman, Anthony Mackie, Sebastian Stan, Tom Holland and Paul Russ are all expected -- but not all confirmed -- to appear in the film.

"Avengers: Infinity War" hits theaters May 4, 2018.
