Bea's fans posted behind-the-scenes photos of her and Richard taping at the General Santos City fish port.
Based on the photos, Bea is seen wearing a short-haired wig for her new TV character.
On September 3, the cast members flew to GenSan, the location of their new ABS-CBN series.
Bea and Richard were joined by Jennica Garcia and returning Kapamilya Rafael Rosell.
Bea posted on Instagram that she would start taping for the new series on September 4.
She wrote in the caption, "Embarking on a new adventure! We're going to start taping for our new teleserye tomorrow! There are so many things going on, so many projects to look forward to and I am enjoying every opportunity that is entrusted to me. Sabi nga nila, TRUST THE JOURNEY."
Veteran actress Helen Gamboa also makes her TV comeback via the still-untitled series, after appearing in the 2017 GMA-7 show Super Ma'am.
During the July 27 story conference of the series, it was revealed that Bea will play the adopted sister of four brothers portrayed by Richard, Rafael, Christian, and Jameson.
The new series will be produced by the unit helmed by Des de Guzman-Tanwangco, under scripted format head Ruel Santos Bayani.
