The Avengers have assembled — and a few other superheroes, too.

Marvel released the highly anticipated trailer for “Avengers: Infinity War” Wednesday, offering the first real look at the 2018 fantasy film that will unite the star-studded casts of both the Avengers and Guardians of the Galaxy franchises.

Highlights from the trailer include Spider-Man’s “spider-sense” tingling for the first time, Black Widow with blond hair and Vision in human form, as well as the first major look at the villain Thanos, who has been teased in several other Marvel films.
