The 38-year-old actress chatted with Entertainment Weekly in a new interview about The Marvels, in which she portrays Kree revolutionary Dar-Benn, the villain of the movie.

Zawe explained to the outlet how she was a bit on the fence before her fiance, Tom, offered her some advice about the role.

Zawe says she had some “incredible conversations” with Tom about the MCU.

“One of the main takeaways from our conversations was: ‘What you put into Marvel, you get back.’ He said, ‘If you go into this with an open heart and a great work ethic and just want to provide an amazing experience for the fans, you’ll have an amazing experience on those sets.’ He really empowered me in that way,” she explained.

On top of his insightful advice, Tom also came with practical advice too.

“He also had some very good practical advice, which was: Make sure you have enough zippers to go to the bathroom in your costume,” she laughed. “Which is very good advice, I realize now.”

Zawe also opened up about her excitement for the flick, which she describes as an “all-female sci-fi extravaganza, with a woman on the other side of the camera.”

“I felt very moved, actually, being involved in it. It’s not an environment you’re often in — a huge-budget movie with all these badass women and Samuel L. Jackson. That just doesn’t happen.”

The Marvels is expected to hit theaters on November 10.

Tom played Loki across many films, which started with 2011′s Thor. He also led the Disney+ Loki series.

The couple, who got engaged a few years ago and welcomed their first child, were recently spotted at Wimbledon this past weekend.
