Is calling "Barbenheimer" – AKA July 21, the day Greta Gerwig’s "Barbie" and Christopher Nolan’s "Oppenheimer" come out on the 2023 movie schedule – the cinematic event of the year too much? It might be, but I really can’t get over how many people have been posting about the amazingness that is these two polar opposite films coming out on the same day. Now, as the promotional cycles for both movies kick into high gear, fans have been rocking "Barbenheimer" T-shirts, and one person had Margot Robbie sign one, and of course, she had the best response.

We’ve been talking about "Barbie" and "Oppenheimer" coming out on the same day for a while now. However, with the film releases coming in a couple of weeks, the discourse has picked up, and there’s even fan-made-merch for the cinematic event. So, as the cast of "Barbie" did press in Australia, a fan showed Margot Robbie her "Barbenheimer" shirt, which featured both the actress’s "Barbie" and Cillian Murphy’s "Oppenheimer" in their wide-brimmed hats. The actress behind the titular character noticed the shirt, and had an A+ reaction to it, as you can see in @mjcooke’s Tweet of the interaction.
