The term "Pene" emerged during the twilight of the Marcos administration and the early years of the Corazon Aquino presidency. Unlike the "Bomba" films of the early '70s, which relied on suggestion and "wet look" aesthetics, Pene movies were notorious for their "patched" sequences—hardcore scenes filmed separately and spliced into the theatrical prints, often bypassing the watchful eyes of the MTRCB (Movie and Television Review and Classification Board).

The 1980s was a significant period in Philippine history, marked by social and economic changes. The country's cinema reflected these changes, with films often tackling themes of love, politics, and everyday struggles. During this era, action films, romantic dramas, and comedies gained popularity, with many iconic actors and actresses emerging.

One of Estregan's most notable films from the 80s is "Sabik" (1987), a romantic drama that explores the complexities of love, family, and social class. The movie follows the story of a young woman who falls in love with a man from a different social stratum, leading to a series of challenges and conflicts. "Sabik" is a prime example of Estregan's versatility as an actor, showcasing his range in playing complex, nuanced characters.
