As Elizabeth Olsen says of the heroes in "Captain America: Civil War," they're "all good and bad." A recent episode of ABC's "Nightline" talked to Olsen and the rest of the "Civil War" cast in a behind-the-scenes look at the Marvel movie's making. Footage from the film's scorching hot Atlanta sound stage pops up throughout the package, which also has interviews with Scarlett Johansson, Robert Downey Jr., Chris Evans, Sebastian Stan and Chadwick Boseman as well as directors Joe and Anthony Russ. One thing pretty much everyone mentions: the film has more to it than just explosions.

"You feel pressure regardless, regardless of the landscape," said Evans when asked if other superhero films have any impact on how he approaches each new Marvel film. "You feel pressure because of the previous films in the Marvel Universe. You almost feel pressure to match your former self."

And while we know that Tony Stark will pop up in "Spider-Man: Homecoming," the actor tells "Nightline" that he may be open to returning for another solo film. "I feel like I could do one more," he said.

Directed by Joe and Anthony Russo and starring Chris Evans, Robert Downey Jr., Scarlett Johansson, Anthony Mackie, Sebastian Stan and more, "Captain America: Civil War" opens on May 6, 2016.
