Margot Robbie, Ryan Gosling, Issa Rae, Kingsley Ben-Adir, Billie Eilish and many more stars came out on the pink carpet. Were only Susan Sontag alive today to rewrite her famous “Notes on ‘Camp,’” she might have had a field day at the “Barbie” movie premiere, which took place at the Shrine Auditorium in Los Angeles on Sunday night (and, for all we know, she might have even been cast in the movie — it seems every other person on Earth appeared in the trailer). If the message of the movie is that all of us are Barbie and Barbie is all of us, the pink carpet did a good job of reinforcing that message (at least that’s what the cryptic trailers imply, but we’re not sure, as no screeners have been made available)
