It's the box-office battle everyone's talking about this summer: Greta Gerwig's "Barbie" and Christopher Nolan's "Oppenheimer" both hit theatres on July 21. The blockbusters couldn't possibly have more divergent plots — the former revolves around the Mattel doll's journey to the real world, while the latter is a biographical drama about the atomic bomb creator — yet film-lovers are counting down the days to dissect each. Buzz surrounding the highly anticipated cinematic event has sparked countless viral memes and, as it turns out, tons of merch. Websites like Etsy and Redbubble are currently packed to the brim with t-shirts, hats, stickers, and even throw pillows that combine "Barbie" and "Oppenheimer" design elements. Some feature the phrase "Barbenheimer," while others superimpose Barbie and Ken in front of a mushroom-cloud explosion or place Cillian Murphy on his own glittery "Barbie" movie poster. A few also incorporate the premiere date, just in case you don't already have your calendar marked and need an additional reminder. Whether you're plotting a double-feature movie day or plan to watch "Barbie" and "Oppenheimer" separately, we found the best Barbenheimer crossover merch so you can rep your two different personalities in theatres and at home. Shop our 15 picks ahead before they inevitably sell out.
