"Barbie" and "Oppenheimer" are only 24 hours away from hitting the big screen, and many people have already bought their tickets for the two of the most anticipated movies of the summer. An example of this is seen at AMC Theatre Cinemas. As reported by Variety, 20,000 people plan to see both films back-to-back and already have their tickets to first see "Barbie," starring Margot Robbie, and then return to theaters to see "Oppenheimer," Christopher Nolan's new feature, or vice versa.

Watching these movies back-to-back isn't casual. This is a direct consequence of the spectacular promotional campaign carried out by both Warner Bros. Pictures (the production company behind "Barbie") and Universal Pictures (the studio in charge of "Oppenheimer"). The idea to see both films back to back on opening day started as a joke from fans. The studios, however, saw an opportunity to promote both films, and soon social media was filled with images promoting both feature films. Several theaters in Spain and Latin America even decided to combine the two feature films and create a single screening with a duration of five hours:

Actors also joined the game. One of the first was Tom Cruise, the star of "Mission Impossible: Dead Reckoning - Part 1." He was the creator of an initiative accompanied by the director of his film that consisted of having several photographs taken with movie tickets and a poster behind some of the summer's other feature films:

The promotion was soon joined by his professional colleagues. In this way, both Margot Robbie and Greta Gerwig posed showing their tickets for the different films in the competition, demonstrating their support for each other's films:

Tom Cruise has even decided that hw will return to theaters to show his support for both blockbusters on the day of their release. In addition, the actor has decided on his viewing order: first, he will watch "Oppenheimer," and right after that he will return to the theaters to see "Barbie":

The battle is about to begin. It remains to be seen whether the film about the physicist who developed the nuclear bomb will win out or whether the public will prefer to enter the world of Barbie and meet the famous doll.
