As SHIROBAKO is an anime about making anime, many anime productions form important parts of the main plot or of characters' backstories. Some are important enough to receive their own articles; if they play a more minor role, they may be listed here instead.
A Certain Temple's Self-Mummified Monk
An anime production advertised as coming out on Blu-Ray and DVD just before the premiere of Exodus! Nothing else is known about it.
Ai Puri
An anime mentioned for which Rena Souma provides voice-acting. Nothing else is revealed about it. Ai Puri may be an abbreviation of the true title.
Big Saga
Described as a large-scale fantasy. Nothing else is known about it.
Corruption Robot: Sadoka Mazoka
An anime production which has Rena Souma as one of the voice actresses, with a movie in the works at the time Souma auditions for I Think My Harem is Slowly Falling Apart, But I Might Just Be Imagining It. Nothing else is known about it.
Cura-Cool! Zero
An anime that is based off of Pretty Cure. Appeared in Episode
Fight
A highly-anticipated show airing in the same season as Exodus! Nothing else is known about it.
G Colle
A highly-anticipated show airing in the same season as Exodus! Nothing else is known about it. "G Colle" may be an abbreviation of the true title, as "Kan Colle" is the abbreviation for the real-life franchise Kantai Collection.
I Think My Harem is Slowly Falling Apart, But I Might Just Be Imagining It (Not Final)
A TV anime for which Shizuka Sakaki has her first (unsuccessful) anime audition. From the working title given and the lines Shizuka delivers at the audition, it seems to be a harem comedy. Or a hentai.
Mon Mon Biyori
An anime mentioned for which Rena Souma provides voice-acting. Nothing else is revealed about it, but the title seems to be a parody of the real-life anime Non Non Biyori.
Space Exodus Idepon
A famous anime that inspired both animation supervisor Ryosuke Endo and 3D designer Yuichiro Shimoyanagi to their respective careers. After a falling out, a showing of the Idepon movie got them back together. It is a parody of Yoshiyuki Tomino's Space Runaway Ideon.
To You Living in the Rainbow City
A 90-minute theatrically released anime viewed by the main characters in Episode 4.
