It's the box-office battle everyone's talking about this summer: Greta Gerwig's "Barbie" and Christopher Nolan's "Oppenheimer" both hit theaters 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.

One person who supports both "Oppenheimer" and "Barbie"? "Oppenheimer" star Cillian Murphy. "I mean, I'll be going to see 'Barbie' 100% — I can't wait to see it," the actor told IGN in an interview published on July 11. "I think it's just great for the industry and for audiences that we have two amazing films by amazing filmmakers coming out on the same day. Yeah, you can spend the whole day in the cinema — what's better than that?" "Barbie" star Margot Robbie and Gerwig have expressed similar sentiments and even posted a photo with their movie tickets next to an "Oppenheimer" poster.

If you're looking to get into the movie-going fun yourself, 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 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 theaters and at home. Shop our 15 picks ahead before they inevitably sell out.
