The picture, shared on Twitter on Thursday, shows producer and president of Marvel Studios Kevin Feige sitting front and center next to Robert Downey Jr., who plays Iron Man, the movie that launched the epic universe in 2008.

"I literally am in the dead center in the front row," 52-year-old Downey Jr. said in a behind-the-scenes video shared shortly after the picture was posted. 

"And I'm looking around and going, 'any one of these people could be dead center.'" 

Sitting behind Downey Jr. is Chris Evans, who plays Captain America, another key character in the MCU. Both are set to appear in the upcoming Avengers: Infinity War, along with the rest of the superhero team, several of whom also appeared in the picture, including Chris Hemsworth , who plays Thor, Mark Ruffalo (Hulk), Tom Holland (Spider-Man), Scarlett Johansson (Black Widow), Jeremy Renner (Hawk Eye) and Elizabeth Olsen (Scarlett Witch).

Also taking a front and center seat, just behind Feige, is Stan Lee, who co-created many of Marvel's famous characters and makes a cameo in every film. 

The Marvel Cinematic Universe has produced 18 movies so far, with its latest installment, Black Panther, set to screen in cinemas worldwide this week. 

Newcomer Chadwick Boseman, who plays the lead in Marvel's latest superhero film, says of the class photo session, "looking around the room, like, what did I do to deserve this?"

Several directors also made an appearance in the picture, including Jon Favreau, who directed Iron Man, Joss Whedon (The Avengers) and Taika Waititi (Thor: Ragnarok).

Several stars, however, were missing from the picture, including Thor actors Tom Hiddleston, who plays God of Mischief Loki, as well as Natalie Portman, who played the God of Thunder's love interest, Jane Foster, in the first two films of the Hemsworth-led series.

Bradley Cooper, the star behind Rocket Racoon, was evidently absent, as Guardians of the Galaxy was represented by lead Chris Pratt, who plays Star-Lord, Zoe Saldana (Gamora) and Vin Diesel, who voices Groot.

Clark Gregg, who played Agent Phil Coulson in The Avengers, and later continued the same role in the Agents of SHIELD television series, shared on his own Twitter account that he was sad to have missed out on picture day. 

So sad I couldn’t make this shoot. Honored to be part of MCU. I was proudly repping #agentsofSHIELD at #MadisonSquareGarden for @NY_Comic_Con @Marvel pic.twitter.com/1TtNtyRbIC
