Caregiver" is Sharon's 30th anniversary offering to her fans and supporters, and also celebrates Star Cinema's 15th anniversary.
Before going to London, Cuneta said she was very happy that she is making her new movie under Star Cinema with acclaimed director Chito Roño at the helm.
But while she was in London, she revealed that for the first time ever, she really had a hard time doing the film because of the very hectic schedule, stress, lack of sleep and unpredictable weather.
"Honestly and quite frankly, I have never experienced such a gruelling schedule and it’s so demanding on my physique. I just fought off trangkaso with very strong antibiotics in fact kahapon lang yung last," Cuneta said
Cuneta worked in London with her co-stars John Estrada, Rica Peralejo, Jhong Hilario and Makisig Morales.
She started shooting the movie April 5th, two days after her contract signing with ABS-CBN's Star Cinema.
"Caregiver" is a story that tackles the hardship of life of an ordinary OFW (Overseas Filipino Worker).
The film will be Cuneta's comeback movie after four years.
