If it's a Marvel Studios movie, it's going to sync up with another Marvel Studios movie.

Ever since "Iron Man," the films under the Marvel Studios umbrella have linked up with one another — even the far-space epic "Guardians of the Galaxy," which features Thanos, the grim, grinning face of evil glimpsed at the end of "The Avengers." It will be no different for "Ant-Man," next summer's all-new superhero movie from director Peyton Reed and starring Paul Rudd and Michael Douglas.

Exactly how "Ant-Man" links with the greater Marvel Cinematic Universe remains to be confirmed, but a new rumor suggests that some characters from the "Captain America" franchise will appear in the first act of the film. Look away now, if you're worried about possible SPOILERS…

According to Latino Review, four faces from the "Captain America" movies will emerge during a prologue sequence centered on Hank Pym, the Ant-Man technology inventor played by Michael Douglas. Those characters are:

Peggy Carter

Howard Stark

Arnim Zola

And a young Alexander Pierce

It's an interesting possibility, one that seems even more likely considering Marvel is about to launch "Agent Carter," an eight-episode ABC series focused on Hayley Atwell's 1940s-era spy, and rumored to include Dominic Cooper's Howard Stark as well. Could this be a sign that Arnim Zola and Alexander Pierce will appear on "Agent Carter," as well — and perhaps even Hank Pym?

Nothing is confirmed, but it's all fun stuff to chew on while we wait to see what Marvel has in store for the small-sized superhero.

"Ant-Man" opens on July 17, 2015.
