Disney held its live-action films panel today at the D23 Expo, and following its presentation of upcoming films such as A Wrinkle in Time and Dumbo, the stage was turned over to Marvel Studios, who focused its time on the highly-anticipated Avengers: Infinity War, unleashing the first-ever look at the film.

Of course, much like with Comic-Con International, the footage presented at D23 was exclusive to the event and presented solely for those lucky enough to get into the panel. However, that didn't stop fans -- and CBR included -- from teasing the first trailer footage.

After bringing out Thanos actor himself, Josh Brolin, Marvel Studios head Kevin Feige went about introducing a good amount of massive cast, including Paul Bettany (The Vision), Elizabeth Olsen (Scarlet Witch), Pom Klementieff (Mantis), Karen Gillan (Nebula), Dave Bautista (Drax), Don Cheadle (War Machine), Sebastian Stan (the Winter Soldier), Anthony Mackie (the Falcon), Benedict Cumberbatch (Doctor Strange), Tom Holland (Spider-Man), Chadwick Boseman (Black Panther), Mark Ruffalo (The Hulk), Chris Hemswroth (Thor), and Robert Downey Jr. (Iron Man). With half of the cast on stage, Feige revealed the first trailer for Avengers: Infinity War.

The footage began with Thor crashing into the windshield of the Guardians of the Galaxy’s Milano ship, with Rocket reacting to him like he’s a bug on a windshield. They bring Thor into the ship, Mantis wakes him up, and Thor asks, “Who the Hell are you guys?”

Thor is heard saying, “Something’s very wrong,” and shots include a distraught-looking Loki holding up the Tesseract, Peter Parker on a school bus with the hair on his arms standing up, and Iron Man standing with the Guardians. “Fun isn’t really something one considers when balancing the universe,” Thanos says, as the teaser then cuts to Gamora’s reaction. “But this does put a smile on my face.”

Quick shots of then seen are Star-Lord, Doctor Strange and Spider-Man all in battle, with the latter in an armroed Spidey suit. Winter Soldier and Black Panther are seen, along with what appears to ban imprisoned Vision, an unmasked Captain America with noticeably longer hair, Iron Man back in what looks like the Hulkbuster armor and Black Widow with blonde hair. Things crescendo with a shot of Thanos using the Infinity Gauntlet, literally throwing a planet at the Marvel heroes.

Marvel Studios will not be releasing the trailer online anytime soon, but those that are in attendance at Comic-Con International next week will more than likely be able to get sneak peek at the footage when Marvel Studios takes over Hall H on Saturday for a two-hour presentation.

Directed by Joe and Anthony Russo, Avengers: Infinity War boasts a sprawling ensemble cast that includes Robert Downey Jr., Josh Brolin, Mark Ruffalo, Tom Hiddleston, Chris Evans, Chris Hemsworth, Jeremy Renner, Chris Pratt, Elizabeth Olsen, Sebastian Stan, Benedict Cumberbatch, Paul Bettany, Samuel L. Jackson, Cobie Smulders, Benedict Wong, Zoe Saldana, Karen Gillan, Vin Diesel, Dave Bautista, Pom Klementieff, Scarlett Johansson, Tom Holland and Anthony Mackie. The film arrives in theaters May 4, 2018, with the untitled sequel opening May 3, 2019.
