Casting

The show stars 2005 Star Circle Grand Questor Erich Gonzales as teenage mom, Nene. This is Gonzales' first starring role in a primetime program. The series showcases showbiz newbies Ejay Falcon and Xian Lim in their first starring role in a primetime series. ABS-CBN picked the cast because they believe that primetime television needs to have new faces, to make it look fresh and better than the usual actors.^[2]

In early July 2009, ABS-CBN released the program's trailer, which revealed the cast of Katorse to include veteran actors Malou de Guzman (as Nene's mother) and Cherie Gil as Gabby's mother, where she plays a less villainous role. Cherie Gil and Erich Gonzales had worked together in Pieta. Gil saw a lot of potential with Erich and believes that she will go far in the showbiz industry.

Sometime in August 2009, the management added Enchong Dee as an additional main cast.^[3]

1968 film

The original Katorse starred 18-year-old Mercedes Galvez, which launched her to stardom in the late 1960s, and featured Antonio Gomez as Gabby and the late Roldan Cruz as Albert. Katorse is known for its sexy trademark "magic kamison" (magic chemise) donned by the young lead actress while out for a swim. Although there are only two male characters in the 1968 film, ABS-CBN management added a third character, played by Enchong Dee, in the television series. The film was remade in 1980 starring Dina Bonnevie.

Postponement

The show was originally scheduled to air in early June 8, 2009, but was postponed as the producers reported having encountered shooting problems because of the weather. Because of this, the management have decided to replace Katorse's timeslot with The Wedding, a romantic-comedy series starring Anne Curtis, Derek Ramsay and Zanjoe Marudo.^[4]

Teenage pregnancy issue

MTRCB has shown concerns due to the show's main theme: teenage pregnancy. They claim that this matter is to be taken seriously and can easily influence viewers. They also referred to The Wedding, another program by ABS-CBN in which the character of Hiyasmin Neri have become pregnant at a young age. MTRCB proclaim that these shows are making teenage pregnancy a stereotype on everyday lives. Although frowned upon, MTRCB have decided that they will take a closer look on these shows.
