The first trailer for Marvel's "Avengers: Infinity War" debuted during "Good Morning America" yesterday.
It's over two minutes long, and it features virtually EVERY major superhero in the Marvel Cinematic Universe, including the Guardians of the Galaxy . . . although you don't see them until the very end.
It includes Black Panther fighting a four-armed alien, Spider-Man in an armored costume, Vision looking human then losing his Infinity Stone, the villain Thanos with two stones in his gauntlet, and a wounded Thor being rescued by the Guardians.
And just to underscore how big this is, the trailer racked up more than 38 million views in its FIRST DAY online.
