The Janitor boasts of an all-star cast which does not take away from the intense storytelling and gritty characters in the film. LJ Moreno plays Dennis's pregnant wife while Dante Rivero plays his alcoholic father and Irma Adlawan as his disabled mother. Nicco Manalo, the son of comedian Jose Manalo, plays the role of a witness tortured in unimaginable ways while the rest of the main cast play suspects in the film. Theater actor Jerald Napoles (from PETA's Rak of Aegis) plays a gun-crazy employee, Alex Medina is a mechanic who likes to bet on “sabong” fight, Raymund Bagatsing is a former policeman turned mechanic owner and Derek Ramsey is a corrupt drug-addicted police operative who has a mistress (Sunshine Garcia from Sexbomb dancers).
The movie intertwines scenes from Dennis's family life, his day job, and his almost perfunctory styled execution of each target. Unlike the usual Pinoy action movie, each scene of violence in The Janitor was necessary and far from gratuitous. Director Michael Tuviera tries to keep his characters interesting enough that audiences get emotionally attached to see them killed off too soon into the story. Hopefully, if the industry can churn out more good stories like this, we can hope to see a resurgence of the Pinoy action genre on the big screen again.
