“Captain America: Civil War” doesn’t hit theaters until May 2016, but a new featurette video gives fans another look at the highly secretive film. While it explains the main struggle -- Captain America (Chris Evans) and Iron Man's (Robert Downey Jr.) argument over if superheroes should follow government regulations -- it also focuses on a few of the supporting characters, like Scarlet Witch/Wanda Maximoff (Elizabeth Olsen).

Kevin Feige, Marvel Studios president, teased how the European superhero has changed between films. “So Wanda Maximoff, for instance, who we saw struggle with her abilities in ‘Ultron,’ we see exactly how powerful she is,” Feige said.

Scarlet Witch was already pretty powerful. She was able to manipulate people’s minds, move objects telekinetically and project energy bolts in "Avengers: Age of Ultron." However, she’ll be more in control of her abilities this time. “She’s more understanding of her skills, and she has quite a great emotional journey in this one,” Olsen added.

The “Captain America: Civil War” featurette is from the Marvel Phase Two Blu-ray set, which was released Tuesday. Watch the video below:

The actress previously hinted that Scarlet Witch’s powers would be more evolved in this movie. “We’re trying to grow her movement as a whole… Jenny [White, movement coach] and I have great pride in trying to make this a huge transformation -- the next time we see her -- of her abilities,” the actress told MTV in September.

As her abilities get even stronger, she’ll have to decide who she wants to help. “She’s coming into her own and starting to understand and have conflict with how she wants to use her abilities,” Olsen told USA Today in October. “It’s a dramatic conflict within her and obviously there’s conflict within the (Avengers) as well.”

It looks like she'll decide to use her abilities to help the patriotic hero. In the video above, Scarlet Witch is seen standing by Hawkeye’s (Jeremy Renner) side, and Entertainment Weekly confirmed that they’ll both be on Captain America’s team in “Civil War.” They might need her formidable superpowers to get them out of trouble in the action film.

“Captain America: Civil War” hits theaters May 6, 2016.
