'Barbenheimer' has been trending online for weeks now - an amalgamation between the hit movies of the season Barbie and Oppenheimer.
Both films have been getting rave reviews, and ticket sales at cinemas across the world continue to grow.
But amid all the hype, there's also growing controversy surrounding the marketing behind the Barbenheimer movement.
Watch: Margot Robbie shows us inside the Barbie dreamhouse. Post continues below.
One of these films is a fantasy comedy film about all things fashion, colour and self-discovery. The other is the Barbie antithesis - a biographical thriller about the makings of a bomb that detonated over Hiroshima and Nagasaki killing over 200,000 people.
It's the latter film that has had a bit of a touchy reception in Japan, given it looks at the man responsible for the atomic bomb that left an indelible mark on Japan's history.
Japan's largest distributor of Hollywood films has yet to announce a release date for Oppenheimer. The film has faced criticism from some for not showing the extent of the devastation in Japan following the atomic bombs being dropped.
As for how Barbie got involved in the drama - this week the official US Twitter account for Barbie positively replied to memes featuring atomic bomb images and Barbie together.
