“Captain America: Civil War” continues to add to the parade of actors returning to the Marvel Cinematic Universe (MCU), but it’s not a superhero this time. Leslie Bibb will return as Christine Everheart.

Bibb announced her appearance on Twitter, although she referred to the film just with a #marvel hashtag. It is worth noting “Captain America: Civil War” appears to be the only MCU movie in production right now.

If Everheart doesn’t ring a bell, it’s likely because she was not a lead but a supporting character. A journalist in the first two “Iron Man” films, she was a Vanity Fair reporter doing a story on Tony Stark (Robert Downey Jr.), and the two ended up having a short fling. After the couple slept together, Tony’s future love Pepper Potts (Gwyneth Paltrow) escorted Everheart out. The journalist attempted to indicate Pepper was always doing small tasks, and Pepper replied she was often tasked with taking out the trash.

Everheart’s appearance likely won’t be as Iron Man’s love interest. She also appeared in “Iron Man 2,” and Tony didn’t seem interested. She’ll probably be shown just doing her job in the movie, and there will be plenty to report on. “Captain America: Civil War” will feature Captain America (Chris Evans) and Iron Man on opposing sides of a public battle.

“After another international incident involving the Avengers results in collateral damage, political pressure mounts to install a system of accountability and a governing body to determine when to enlist the services of the team,” the official synopsis says. “The new status quo fractures the Avengers while they try to protect the world from a new and nefarious villain.”

Bibb is just the latest in a long line of additions to the cast. Marvel Studios President Kevin Feige reportedly confirmed that Spider-Man (Tom Holland) also would join the cast of “Captain America: Civil War.” Previously, a long list of superheroes were confirmed for the film, including Black Widow (Scarlett Johansson), Hawkeye (Jeremy Renner), Black Panther (Chadwick Boseman), Falcon (Anthony Mackie) and Scarlet Witch (Elizabeth Olsen). “Civil War” appears to be overflowing with superheroes, so don’t expect Bibb to get too much screen time.

“Captain America: Civil War” is scheduled to hit U.S. theaters May 6, 2016.
