Thai Hoa (geology: Sun in the dark)
After a long journey in cinema, experiencing impressive comedy and bi role, Thai Hoa participated for the first time in a war and historical film project by director Bui Thac Chuyen, "Tunnel: Sun in the dark". The film premiered in April during the 50th anniversary of the Liberation of the South and National Reunification. The film reached the 170 billion VND revenue mark.

Thai Hoa said that he had practiced with props for a long time, to the point that when going to bed, he also held props to get the feeling of a festival "going to bed, he also held a gun".
Thai Hoa played the emotional Bay Theo, he acted realistically, vividly, with many contributions.
Tuan Tran (Mai and Mang me di di)
Tuan Tran is considered the strongest opponent of "million-dollar actor" Thai Hoa on the list of nominees for Best Actor in the category of feature films.
Tuan Tran has 2 male leads participating in this Golden Lotus film. Both roles with 2 different colors show the real strength of Tuan Tran.

With the role of Sau in the movie Mai, Tuan Tran revealed his complicated inner acting style, Sau is both playful, free-spirited, and in a committed relationship. Sau was caught between the conflict between his mother and Mai - his beloved brother. Tuan Tran plays a manly, open-minded, emotional and realistic character.
Playing the role of Hoan in "Bringing mother away", Tuan Tran plays the role of a poor young man, working as a street barber, having to take care of his mother with Alzheimer's disease. In "Bringing Me Go" (Getting Me Go), Tuan Tran had many thanic acting scenes.
Every time he held a scissors to greet customers on the roadside, Hoan brought different emotions and sufferings. The scene of holding scissors to greet guests with old melodies while trying to hold back so as not to cry but tears still flowing, Tuan Tran depicts the character's suffering, touching the hearts of the audience.
What is special is that in both films, Mai and Mother Goes Out Tuan Tran both acted with Hong Dao. They played mother and daughter in both works but had different fates, circumstances, and psychological developments.
Both Hong Dao and Tuan Tran have their mark and excellence in acting, bringing strong emotions to the audience.
Thanh Son (In air combat)
Thanh Son made a surprise in 2025 when he stepped from the small screen at golden hours to the big screen, continuously participating in projects "Love by mistake for a best friend", to "death in the air".
The biggest mark, considered a breakthrough in Thanh Son's career, was the role of bodyguard Binh in "The War in the Air".

Binh is a "heavyweight" role in "The War in the Air". The role is long, consistent, with many dramatic and suspenseful actions that take place continuously.
Shooting in the narrow space of the airliner compartments caused the action scenes to be difficult, complicated, and constantly hit. In close-range scenes in a narrow space, Thanh Son performs them forcefully, aggressively, and convincingly.
Thanh Son deserves a place in the nomination list for Best Actor in the category of a documentary at this Vietnam Film Festival.
Do Nhat Hoang (Red Rain)
Nhat Hoang started out as a model. He has a small role in Tran Thanh's film "Mai". Nhat Hoang has appeared in "Once Upon a Time There Was a Love Story", "Saigon in the Rain"... but it was not until "Red Rain" that he really made his mark.
In Red Rain, Nhat Hoang plays Cuong - a volunteer Conservatory of Music student who joined the army and supported the Quang Tri battlefield in 1972,

Cuong and his teammates had days of fighting and forgetting themselves to protect the ancient citadel.
Nhat Hoang has been dedicated to performing, investing and making many efforts. Cuong's role is considered one of the most memorable roles in Do Nhat Hoang's career.
With the role of Cuong in the film "Red Rain", Do Nhat Hoang will also be a strong candidate for the Best Actor Golden Lotus Award at the 2025 Vietnam Film Festival.
