Myrna Castillo is a veteran Filipino actress who has appeared in numerous films and television shows. Her career spans several decades, and she has been a part of the Philippine entertainment industry since the 1970s.

Did Sharon Cuneta and Myrna Castillo ever share a film? No. But their names were once linked in a bizarre 1988 tabloid headline: “Myrna: I’d Rather Do Pene Than Be Like Mega – Too Much Pressure.” Castillo allegedly told Police Weekly that being a virgin-role model like Sharon was “more suffocating than removing clothes on camera.” The quote was later denied, but it fueled a brief media rivalry.

Another intersection: Director Peque Gallaga. He made the pene masterpiece Scorpio Nights (1985) but also directed Sharon in the wholesome fantasy Magic Temple (1996) — proof that 80s directors often jumped between pene and mainstream.


The 1980s in Philippine cinema was a decade of glitter and grit. On one hand, you had the mainstream explosion of the “Mega” — Megastar Sharon Cuneta — ruling the box office with romance, drama, and family-centered vehicles. On the other, a parallel industry thrived in the shadows of “pene” movies (a colloquial term from “penetration,” referring to softcore sex films), where daring actresses like Myrna Castillo became queens of the midnight screen.

This article explores the bold world of 80s Pinoy pene films, Myrna Castillo’s iconic status within that genre, and how the term “Mega” came to define a completely different brand of stardom.


For the past decade, finding a clear copy of a Pinoy pene movie from the 80s was impossible. They existed only as grainy, 3rd-generation VHS rips with tracking lines. However, the last 24 months (2024-2026) have seen a "Mega New" boom.

Why now?
