Speaking at a special screen talk Sunday at the BFI London Film Festival, Greta Gerwig recalled her experience making 'Barbie' and said the film was most joyful set she’s ever been on. “So, I thought, if I can make a movie that is half as fun to watch as it was to make, I think maybe we’ve got a shot.” During Barbie‘s opening weekend, Gerwig said she was in New York, but she didn’t wait to hear about the reaction to the film from other people, so she went to get answers for herself.
