Looks like those recent rumors

According to The Wrap, Boutella (who’s set to appear in Star Trek Beyond next year as well)—has joined the project, which was allegedly floating around alternate scripts by Jon Spaihts depending on if a man or a woman was cast. Of course, Boutella’s not the only actor linked with the film. Recent rumors
It’s cool to see a woman land the role—especially as, beyond The Mummy, Boutella would now star in multiple Universal Monsters films as part of plans for a Marvel-esque shared universe. As long as this is just a straight up sinister Mummy who happens to be a woman, rather than a cliché “Yummy Mummy” (ugh), that is!
