Summer Film ni Notte (2021)

Both the main characters are directors with short hair, and they made a historical film during summer vacation. The dramas also features friendship and rivalry on romance. The main characters’ friend was also used an actress in the film. The main actor for the film was the main characters’ love interest.

Both are about making a samurai movie, even though the latter is way more bloody and violent than the first one

The story is quite similar, about students who want to make a film and it is accompanied by fantasy elements.

Both are love letter for filmmaking but more importantly shows how good Japan can be when they decide to think outside the box and get those creative juice flowing.

Despite different settings, both possess similar sense of humor and zero-to-hero narrative (although in "Summer Movie" it's not the main message). The main leads are also mostly girls too.

Both basically in the same brethren - a bunch of kids in school setting doing DIY stuff (Summer Film is movie, Linda is music). The pacing and zero-to-hero plot of both shows are similar.
