GILDA OLVIDADO was born in Cebu City, Cebu, on 9 August 1957. She is the daughter of Gregorio Tan and Guarda Olvidado. She grew up and has her early education in Maranding, Lanao del Norte. She studied Chemistry for a year at Adamson University and Journalism for two years at Manuel L. Quezon University, however, she did not finish college. When Gilda was in her teens, she greatly admired Carlo J. Caparas who influenced her to venture a career in komiks writing.
Her first komiks serial attempt was a comedy, Cha Lee’s Angels, a take-off from a then highly popular TV detective series. The serial rated fairly enough. Then the Atlas Publishing management commissioned her to do a drama. That second serial, Kapag Puso ang Nagsasakdal, got a satisfactory rating. It was to be turning point in her komiks career – she discovered that drama is her forte. From then on she was well on her way, writing as many as fourteen novels which run simultaneously weekly.
The success of her previous works became the turning point of her career and she was in demand, writing for romance novels for Valentine Romances, Twin Hearts, and Gemini pocketbooks, and Dahlia, a radio serial which was notably aired over DWWW. It was in 1993 that she decided to start publishing her own line of novels. Aside from the more popular works she has done, Gilda also writes erotica for the Abante tabloid, particularly in the Brilgint section.
She authored the komiks-novels that became blockbuster movies, like Sinasamba Kita (1982), Dapat Ka Bang Mahalin? (1984), Kung Mahawi man ang Ulap (1984), Ina, Kasusuklaman Ba Kita? (1985), Huwag Mo Kaming Isumpa (1986), Pinulot Ka Lang sa Lupa (1987), Saan Nagtatago ang Pag ibig (1987), Huwag Mong Itanong Kung Bakit (1988), Magkano ang Iyong Dangal (1988), and Babangon Ako at Dudurgin Kita (1989).
She wrote the sreeenplays for the following films: Tayo na sa Dilim (1990), Maya (1990), and Bakit Kay Tagal ng Sandali (1990). She was a co-writer for some Filipino telenovelas which adapted some of her works like Sinasamba Kita (2007), Kung Mahawi Man ang Ulap (2007), Babangon Ako’t Dudurgin Kita (2008) and Dapat Ka Bang Mahalin (2009). She is also the co-writer of some afternoon melodramas like My Only Love (2007-2008) and Kaputol ng Isang Awit (2008).
Her story for the movie Saan Nagtatago ang Pag ibig won the 36th FAMAS Award for Best Story. Olvidado was also nominated by the FAMAS for Best Story for the films, Sinasamba Kita (1982), Kung Mahawi Man ang Ulap (1984), at Huwag Mong Itanong Kung Bakit (1988).
