The curtain doesn’t just rise in Ang Babae Sa Septic Tank 4: Oh Sh*t! It’s Live Sa Cheter! it is getting pulled back.

Running from June 19 to August 16, 2026 at the PETA Theater Center, the fourth installment of the Septic Tank franchise shifts its razor-sharp satire to live theater. If the first film skewered the indie scene, the second mainstream cinema, and the third historical revisionism , this time the target is closer to home: the rehearsal room, the production meeting, the fragile ecosystem of mounting a show.

At the center is Eugene Domingo, returning as an amplified version of herself. Ambitious, self-aware, and navigating the absurdities of bringing a live production to life. Domingo’s legacy with the franchise is no small footnote; the original Ang Babae Sa Septic Tank became the highest-grossing Filipino independent film of its time. Beyond the accolades under its belt, the film has become a pop culture staple and one of the most influential films of its time.

Here’s who’s stepping into the meta-madness with Uge:

Meann Espinosa

A longtime PETA artist and director, Espinosa brings both performance experience and behind-the-scenes insight into rehearsal room dynamics — making her casting especially pointed in a play about creative tension. 

Stella Cañete-Mendoza

With decades of stage work and major acting awards to her name, Cañete-Mendoza adds veteran authority to a production that examines how artists hold space — and sometimes clash within it.

JC Santos

Known for balancing theater discipline with mainstream screen success, Santos represents the crossover performer — equally at home in intimate stage work and wide-release films

Andoy Ranay

A director with strong roots in youth-driven screen projects, Ranay steps into the live arena, blurring the line between creator and character. 

Marlon Rivera

The filmmaker behind the original Septic Tank trilogy now appears within its theatrical evolution — layering the satire with insider self-awareness

Joshua Lim So

An award-winning writer with a strong literary background, Lim So plays the playwright caught in constant rewrites — a role that feels both meta and fitting.

This installment promises to expose “the messy, hilarious, and painfully relatable process of making theater in the Philippines today.”

In a cultural moment that often highlights polished premieres and curated press junkets, Septic Tank 4 focuses on what usually stays unseen: revisions that spiral, egos that bruise, scripts that evolve under pressure, and the delicate negotiations required to keep a creative vision intact. 

The creative team underscores that insider perspective. The play is written by Chris Martinez, the force behind the original trilogy , and directed by Maribel Legarda, who previously helmed major PETA hits like Rak of Aegis and One More Chance The Musical. It’s satire built by practitioners who understand exactly what they’re dissecting.

And perhaps that’s the most compelling part. The chaos isn’t there to diminish the art form. It’s there to reveal its humanity.

Tickets are expected to sell quickly , and if history has proven anything, it’s that the Septic Tank franchise thrives when it holds a mirror up to its own industry. This time, the reflection is lit by stage lights and it’s unapologetically live.
