While we're all talking about both the WGA/SAG strikes and Barbenheimer, I hope everyone realises that the entire reason this exists is because Christopher Nolan stood up to Warner Bros against pushing their entire cinematic slate onto streaming in 2021, by taking his next film to another studio.

Then, as an act of petty revenge, they decided to deliberately move their single biggest movie of 2023 (and arguably WB's biggest non-Batman/Harry Potter movie in DECADES) directly onto his release date.

So no, the Barbie Marketing isn't "so good it helped another movie". The Barbie Marketing Machine was specifically designed to get back at someone who dared to stand up against WB executives.

It was a calculated move of malice by soulless corporate fuckeroonies.
