"Coupez!" was originally titled "Z (comme Z)" until Ukrainian filmmakers pleaded Michel Hazanavicius to change the title. The reasoning for this is the use of the letter "Z" painted on the tanks of the Russian army in their invasion of Ukraine.
The 32-minute movie was rehearsed for five weeks before the shooting, and took four days to shoot. It is not a unique shot, as there is one single cut for technical reasons at some point (so it's actually two long shots).
Director Michel Hazanavicius had wanted for a long time to direct a comedy about a movie shoot and was in the process of gathering ideas for a new movie. When producer Vincent Maraval showed him Zombis, Cámara, ¡Acción! (2017), a Japanese movie whose rights he had just bought, Hazanavicius loved it and accepted to direct a remake.
The whole movie was shot in six weeks in the Évry racetrack, for a very limited budget of 4 million euros.
To sell the concept of the movie-within-the-movie to the audience, Yoshiko Takehara reprises her role as the movie's producer. Director Michel Hazanavicius said that her character makes the whole project believable.
