Greta Gerwig was bummed her film babies Timothée Chalamet and Saoirse Ronan were too busy for Barbie
The Little Women costars were supposed to do cameos in Greta Gerwig's film, but it was scrapped due to scheduling conflicts

There comes a time in every mother’s life when she must come to terms with the fact that her babies—her little women, if you will—are going to grow up, develop their own passions and interests, and not be so keen on playing with dolls anymore. (You can go ahead and play “Return To Pooh Corner” while reading the rest of this article.)
That sad time has arrived for award-winning director Greta Gerwig, who recently opened up about how “annoyed” she was to have to do Barbie without her biological children Saoirse Ronan and Timothée Chalamet, who were originally could have made special cameo appearances in the film. Okay, so she didn’t literally give birth to Jo March and the future Mr. Wonka, but we’re sure when you’ve come up together the way these three have, the ache is similar. (Something Gerwig actually probably understands quite well, considering the subject matter of the trio’s first collaboration, Lady Bird.)
