The film production is home to its homegrown stars, mostly Regal babies like Romnick Sarmenta, Sheryl Cruz, Rey "PJ" Abellana and Gretchen Barretto as well as talents inside Seiko like Jestoni Alarcon, Ian Veneracion, John Regala, Cesar Montano and Rita Avila.
Among its most memorable productions during its early years are The Life Story of Julie Vega and Blusang Itim, as well as horror flicks Huwag Mong Buhayin ang Bangkay, and Hiwaga sa Balete Drive.
It was in 1995 when it increased its production in ST films, with Rosanna Roces, Priscilla Almeda, Natasha Ledesma, Leandro Baldemor and Gardo Versoza in its stable of talents.
Seiko produced movies later like Bridal Shower (2003), the mockumentary Bikini Open (2005), the family comedy I Wanna Be Happy (2006) and the psycho-erotic thriller Silip (2007).
In 2007, Seiko was reportedly suspended by the Movie and Television Review and Classification Board (MTRCB) due to the prominence of the production of erotic films.
