The film "The Devils Prince" marked Luong The Thanh's challenging choice. After more than a decade of actively stepping back to television and being a behind-the-scenes player for his wife to develop, the actor decided to return to cinema with the role of Lo Dat - a strong and upright village chief in a historical - horror setting. Character requires physical strength, inner acting ability and handling many actions.
To fully transform, Luong The Thanh went through a period of strict "d betterment" in body. He lost 5 kg, completely cut the starch in more than 3 months, only ate vegetables and boiled food, combined with high-intensity exercise to own a "6-bag" body. Thuy Diem said she "heartbroken" but respected her career choice, considering it her husband's seriousness when he returned.
Sharing at the event, Luong The Thanh said he took the initiative to audition so that the director could evaluate his suitability. During practice and filming, he was injured while practicing martial arts, and when he went to Da Lat to film, he still had to be sprayed with oil due to back pain. "I was shy, nervous and moved when the audience welcomed me back after 13 years. The words of encouragement on the red carpet are a great source of energy for me to continue with cinema, he said.
The film "The Prince of the Devil" is adapted from the horror novel "The Legend of Ly Trieu", set in the Ly Dynasty. The film tells the story of Prince Than Duc (Anh Tu Atus) - a man with ambition to free the evil Xuong Cuong, confronting the village chief of Lo Dat in the battle between justice and evil. The project is directed by Tran Huu Tan - who made his mark with "Cam" and "The soul Eater", and is expected to be released in theaters nationwide from December 5, 2025.
