Romijn kept her lips sealed when asked if she’s read the entire script, noting, “I cannot confirm nor deny that I have read the entire script.” She also admitted she “can’t say” who she’s filmed scenes alongside, but it was a “surreal” experience shooting with some of her original X-Men co-stars with a new, blended cast.

The actress reprises her past X-Men role as the shapeshifting mutant Mystique in the Marvel Cinematic Universe event film, which set up shop in the U.K. She also recently wrapped filming season 4 of Strange New Worlds in Toronto and will return to film season 5.

Avengers: Doomsday kicked off production in April, and this star has already filmed several scenes but isn't sure if they're done filming since the script isn't finished.
