ANAHEIM, Calif. — A hair-raising teaser trailer for “Avengers: Infinity War” stole the show at the star-studded presentation of the Walt Disney Studios upcoming live-action films at the studios’ fan convention D23, upstaging even “Star Wars: The Last Jedi,” Oprah Winfrey and Mary Poppins.

“Star Wars” fans did get a little morsel of footage in a behind-the-scenes featurette from the upcoming space saga and a lively panel with the film’s writer-director Rian Johnson and a few of the film’s stars. But audiences have yet to see a full trailer for the film.

Instead, it was the ultimate Marvel Cinematic Universe team-up “Avengers: Infinity War” that got fans really excited.

Marvel Studios head Kevin Feige was on hand with a stage full of stars that included Robert Downey Jr. as Iron Man, Chris Hemsworth as Thor, Benedict Cumberbatch as Doctor Strange, Tom Holland as Spider-Man, Sebastian Stan as The Winter Soldier, Elizabeth Olsen as The Scarlett Witch, and Josh Brolin as the ultimate bad guy Thanos.

The trailer, which has not yet been released online, was packed to the brim with tantalizing scenes, including Thor, floating and near dead in deep space being rescued by the Guardians of the Galaxy; Spider-Man’s hair standing up on his arm; Tony Stark ominously warning that, “He’s coming for us,” likely talking about Thanos; and Thanos himself gripping a weakened Thor’s skull and looking ready to crack it with ease.
