Now we know just why Joe and Anthony Russo, the directors of "Avengers: Endgame," last week declared Monday the conclusion of the #DontSpoilTheEndgame campaign, which kicked off with their April 16 open letter to fans, urging them not to spoil "Endgame" "for others, the same way you wouldn't want it spoiled for you."
On Monday morning, Sony and Disney released a trailer for this summer's "Spider-Man: Far From Home," the sequel that serves as the end of Phase 3 of the $21 billion Marvel Cinematic Universe. Hot on the heels of "Endgame's" second massive weekend, "Spider-Man" star Tom Holland opens the three-minute trailer by saying directly to the viewer: "If you haven't seen 'Avengers: Endgame' yet, stop watching, because there's some serious spoilers about to come up.
"But if you have seen 'Avengers: Endgame,' enjoy the trailer."
And with that, Sony and Marvel have pulled off a rather sly feat - simultaneously piggybacking on the peak interest in "Endgame" while also creating an extra incentive for lagging MCU viewers to get thee to a theater quick to see how the Avengers film ends.
The "Spider-Man" teaser, in other words, exploits the interconnectedness of a cinematic Universe like few trailers can.
