Russo Brothers Tease Clues in Avengers: Doomsday Trailers, Marvel Launches Countdown

Marvel Studios has cranked the hype for Avengers: Doomsday into overdrive.

Alongside the official release of the recent trailer—which features Fantastic Four’s Thing, Namor, and the warriors of Wakanda—the Russo Brothers have returned to the spotlight, teasing that the footage fans have been watching may hold more than meets the eye.

“What you’ve been watching for the last four weeks
 are not teasers. Or trailers. They are stories. They are clues
 Pay attention,” the Russos posted on social media.

The post is accompanied by the hashtag #DoomsdayHasBegun, setting the stage for a deeper mystery surrounding the film.
