Elizabeth Olsen has voiced support for her Avengers co-star Scarlett Johansson amid the actress's lawsuit against Disney over the release of Black Widow.

Olsen, who plays Scarlet Witch in the Marvel Cinematic Universe and stars in the popular WandaVision series on Disney+, commented on the legal battle in a joint interview with Vanity Fair along with Ted Lasso actor Jason Sudeikis.

"I think she's so tough and literally when I read that I was like, 'good for you Scarlett'," Olsen said.

When asked about the issue of cinema releases at a time when they are still in recovery due to the Covid-19 pandemic, Olsen replied: "I'm worried about a bunch of things. Not worried on Scarlett’s behalf.

"But I’m worried about small movies getting the opportunity to be seen in theaters. That was already a thing pre-Covid. I like going to the movies and I don’t necessarily want to see only an Oscar contender or a blockbuster.

"But when it comes to actors and their earnings, I mean, that's just, that’s just all contracts. So it’s either in the contract or it’s not."

Meanwhile, Sudeikis also expressed his admiration for Johansson, adding that it was "appropriately bad-ass and on brand".

Johansson launched legal action against Disney in July for breach of contract for streaming the film Black Widow on the Disney+ channel at the same time as the cinema release.

Disney responded by saying there was "no merit" to the Johansson's claim, saying it had complied with her contract.

The Marriage Story actor held that the dual release strategy of Black Widow had reduced her compensation, which was based partly on box office receipts from what was supposed to be an exclusive run in cinemas.
