Scarlett Johansson says her pregnancy will not affect the filming of Avengers: Age of Ultron.
The actress, who will reprise her role as The Black Widow, said that filming on the superhero follow-up is going "full steam ahead", while Marvel Studios president Kevin Feige confirmed that the script has not been changed.
Johansson told the Huffington Post: "We start shooting in three weeks and I'm stunt training and we're good to go.
"You know, I think it's something that is hard to talk about, exactly. You know, trying to skirt around your question exactly - and, you know, doing a poor job of it.
"But, you know, like I said, everything is exactly on schedule. Everything is going just fine. The Black Widow always wins and will continue to."
Feige commented on Johansson's pregnancy news on movie website Collider: "Well my first reaction was I was very happy for her and very excited for her, and my second reaction was we've gotta move some pieces on the chess board around schedule-wise.
"But we didn't change the script at all, which is sort of the most important thing for us in terms of the storyline. I think the goal is for us to sit here talking about the fact that you would never know that Black Widow was pregnant during the filming of the movie when you see the final version of Avengers 2."
Buffy creator Joss Whedon is directing the sequel which features an all-star cast including Robert Downey Jr, Aaron Taylor-Johnson, Elizabeth Olsen, Samuel L. Jackson, Chris Evans, Chris Hemsworth and Mark Ruffalo.
Avengers: Age of Ultron is scheduled for release on May 1, 2015.
