Upon returning home, he reunites with the Escalera brothers (Tito Sotto and Joey de Leon), who have become successful real-estate developers.
They include Anthony Roquel (Tonette Macho), Mely Tagasa (Miss Tapia), Sharon Cuneta (Sharon Escalera), Redford White (Redford), Ariel Villasanta (Pekto), Bibeth Orteza (Bibeth Belibet), Kaye Torres (Kaye Flores) and Richie D'Horsie (Richie "Kabayo").
Vic Sotto first revealed during a 2007 episode of the GMA documentary show I-Witness that he wished to do a reunion movie with the surviving cast members of Iskul Bukol.
The title was changed to Escalera and Ungasis: 20 Years After, which reunited the main characters for the first time since the original TV series.
The movie's title was changed again to Iskul Bukol 20 Years After: Ungasis and Escaleras Adventure in order to gain strong audience recall, owing its large fanbase to people who grew up during the TV show's original run.
Vic Sotto, Ryan Agoncillo, and Jose Manalo joined the crew in shooting the foreign scenes in Cambodia from October 7 to 14.
On the positive side, Phillip Cu-Unjieng of the Philippine Star said the film appealed to young viewers because of the action-adventure element, while older fans of the show can relate to the characters that come back after a long time.
