One hopes not since Gerwig likely wouldn't be involved and Robbie and Gosling didn't sign a multi-picture deal.
I think a sequel with a really good idea behind it might be cool, but some stories should be one and done and I don't really know that any more needs to be said with live-action Barbie.
Meanwhile, Mattel has licensed 14 other properties for movies.
Yeah, I'm not against sequels in principle. Sometimes I just want to have another trip to whichever world the movie takes place. Barbie though... I love that movie, but I really don't see any way to make any sort of sequel and have it be good.
