Tony Stark and Michael Keaton’s Vulture school Peter Parker ‘Spider Man: Homecoming’ Trailer

THE LESSONS come fast and nearly injurious for the new young Spidey.

The official trailer for this summer’s “Spider-Man: Homecoming” has landed, and as we saw in last year’s “Captain America: Civil War,” Tom Holland’s frisky Peter Parker is being mentored with an iron-firm hand by Robert Downey Jr.’s Tony Stark. And the central theme of this nearly three-minute sneak peek, naturally, is the growing pains involved in a boy becoming a Spider-Man.

This Peter Parker is so eager to join the Marvel big boys in Stark Tower that he even watches Avengers videos on his laptop (we glimpse him watching an old-school “Captain America’s Fitness Challenge”).

“Can’t you be just a friendly neighborhood Spider-Man?” Stark replies when Peter eagerly asks how he can become an Avenger. Stark also advises: “Just stay close to the ground” in Queens before trying to save the world. (Never mind that Stark himself drafted Peter into a huge Avengers melee in Europe in “Captain America: Civil War.”)

But then Michael Keaton’s Adrian Toomes — a.k.a. the Vulture — drops in to declare: “The rich and the powerful, like Stark, they don’t care about us!”

The Vulture is using his robotic winged suit to terrorize New York, with Bokeem Woodbine’s Herman Schultz/Shocker by his side. Spider-Man soon tries to stop him, as the Vulture aims to slice a ferry in half. Many would have been hurt if Iron Man hadn’t flown in to save the day.

“Forget the flying monster guy,” the paternalistic Stark tells Peter about Vulture. “There are people who handle this sort of thing.”

“I was just trying to be like you,” Peter replies, looking up.

“If you’re nothing without this suit, then you shouldn’t have it!” snaps Tony of the Stark Industries-designed costume.

And with that, the dramatic dynamic is set into motion.

(Meanwhile, there are still no clues as to whether Zendaya’s “Michelle” is actually future Spidey flame Mary Jane Watson — but then again, a big surprise like that is unlikely to be revealed in a trailer.)

“Spider-Man: Homecoming” is Marvel Studios’s first attempt to mend Sony’s once-irresistible character, who lost some box-office luster with Andrew Garfield’s second outing. Now, the fate of the franchise rests with 20-year-old Tom Holland.
