- Celso Ad Castillo is ranked along with Directors Lino Brocka, Ishmael Bernal, Marilou Diaz-Abaya and Mike de Leon for bringing about the Philippine cinema’s so-called Second Golden Age in the 70s.
- Castillo was also known for such classic as Nympha, an erotic film ahead of its time; Celso Ad Castillo made his mark in local movies by creating a stir in the early '70s, with his sex flicks which were once even condemned as "pornography." His original Nympha was hailed as one of the best movies of the decade, along with his Asedillo. Nympha became the second Filipino movie that qualified for competition category in the 1971 Venice Film Festival, after Manuel Conde's Genghis Khan. Nympha was shot in black and white and starred a relative newcomer whom Celso simply christened as Rizza (Estrella Fabian in real life). The film earned for Celso his first Famas nomination as best director, up against Gerry de Leon's "Lilet," which starred Celia Rodriguez.
- Celso further reinforced his reputation as director of sex flicks with "The Virgin" which again starred Rizza, "Ang Pinakamagandang Hayop sa Balat ng Lupa" with Gloria Diaz in the original version and Ruffa Gutierrez in the remake, "Ang Madugong Daigdig ni Salvacion with Pilar Pilapil, "Virgin People" with Pepsi Paloma, Janet Bordon and Myrna Castillo, "Isla" with Maria Isabel Lopez, "Brown Emmanuelle" with Myrna Castillo and "Paradise Inn" with Lolita Rodriguez and Vivian Velez.
- Burlesk Queen (1997), which starred Vilma Santos, gave Celso his first best director award, besting other film greats such as Lino Brocka, Ishmael Bernal, Mike de Leon, Eddie Romero and Augusto Buenaventura
- Celso also directed Christopher de Leon in Ang Alamat ni Julian Makabayan, Dante Rivero and Hilda Koronel in Ang Gangster at ang Birhen, Jay Ilagan in Ato Ti Bondying, Elizabeth Oropesa in Uhaw na Dagat, Lito Lapid in Pedro Tunasan (1983), Dina Bonnevie and Gary Estrada in Tag-araw, Tag-ulan, German Moreno in Payaso, Gloria Diaz in Ang Daigdig ay Isang Butil na Luha, Sunshine Cruz in Lihim ni Madonna and Ramon Zamora in Ang Mahiwagang Daigdig ni Pedro Penduko (1973) and Return of the Dragon (1974).
