It stars Juan Karlos Labajo, Sarah Holmes, and an ensemble cast of Johnrey Rivas, Marlo Mortel, Cassy Legaspi, Joaquin Domagoso, Nicole Laurel Asensio, JM Yosures, Adelle Ibarrientos, Vean Olmedo, Jomar Tañada, Brae Luke Quirante, and Bodjie Pascua.

[5] In writing the film, Tañada consulted historian Michael "Xiao" Chua, archivist Karl Patrick Suyat of Project Gunita, and Rebecca Quijano, who witnessed Aquino's assassination, to ensure the accuracy of scenes depicting historical events regarding Aquino, such as his assassination and his sentencing by a military commission to death.

[6] Tañada considered actors Piolo Pascual and Jericho Rosales before choosing Juan Karlos Labajo to play Aquino in the film.

Cifra earlier collaborated with Tañada for Katips, a similar film detailing the life of activists during Marcos' martial law regime.

[8] Tañada served as the lyricist for the musical's songs, with the exception of Buwan, which was written and released by Labajo in 2018 and performed using a different rendition for the film.
