Hit wo Nerae!

Young female lead in movie/series making industry. Both of these works showcase the proces of creating fiction and various takes on creative vision. 

Cosprayers is a movie and Smash Hit is like movie about movie . Both are crappy but somehow still manage to be funny and both have in my opinion great soundtracks made by same composer . Also Cosprayers explains lot of stuff that happened in Smash Hit and vice versa . 

Also Cosprayers (TV) and Cosprayers (Movie). All of these are the show that they are making during Smash Hit! with the same characters, but now they are playing their roles in the show. 

Both have themes of business behind anime.
