Culture Chop Suey is a Fantasy Counterpart Culture cobbled together from two or more real world cultures. As with an Anachronism Stew, the reasons for this can vary from case to case. It can stem from the writer's ignorance on the subject: they …

In my opinion some times to create a culture chop-suey, mixing elements from different civilitations from real world could be necessary for reasons of politically correction, to avoid if that nation was used as antagonist faction, then lots of pejorative traits were added to their people.

False Myths About Spain in Films: Some of the Funniest Mistakes - don Quijote's Spanish Blog
Mission Impossible II
To begin with, let’s look at one of the best known and extravagant examples: Mission Impossible II. In the film, Tom Cruise lives a unique experience: Holy Week in Seville, the Fallas in Valencia, and San Fermines in Pamplona, all together in the same scene. (In fact, not only do these festivals take place in different cities, they also happen at different times during the year.) Anthony Hopkins (Swanbeck in the film) himself is amazed and puzzled at such a spectacle: "Festivals are a pain in the ass. Honoring their saints by setting them on fire. Let's you know what they think of saints, doesn't it?” We Spaniards were even more perplexed at these tremendous cultural misconceptions. (For the record, saints are not burned in any of the three separate festivals untruthfully mixed together here.)
Knight & Day
Oops, he did it again! Tom Cruise messed about with Spanish traditional festivals once more. On this occasion, he and Cameron Díaz attend very peculiar bull runs or encierros and run in front of a herd of eight steers and two placid bulls. In addition, this recreation of the San Fermines of Pamplona was actually filmed on Calle Ancha street in Cadiz, and (due to the script's demands) ended in the Maestranza bull ring in Seville.
