Actress Rachel McAdams will appear in the film, but she’ll not be the one pregnant.
She’ll be in a role called “Bodacious”, which will have her pregnant.
“The only time I’ve ever been pregnant is when I was in a movie with a baby,” McAdams told Entertainment Weekly.
“But that was so long ago, I don’t think it’s ever going to come up again.”
The news comes as McAdams is pregnant with her third child.
She recently revealed that she’s expecting her fourth child, a girl named Isabelle.
