Two generations of Vien's role in '1 millimeter away from you' attract attention
Ha Viet Dung and young actor Son Tung made an impression when playing the role of Vien. The similarities in appearance and the connection between the two generations created the appeal of the film.
In the TV series "1 millimeter away from you", the character Vien in two stages of adolescence and adulthood is receiving great attention from the audience. This role is played by young actor Son Tung (young Vien) and actor Ha Viet Dung (adult Vien), both of whom have made their own mark and received many positive responses.

The special connection between two generations of actors
The similarities between the two versions of Vien's character are not only in appearance but also in the spirit of the role. Actor Ha Viet Dung shared that he felt pressured because the young actors in the first part, especially Son Tung, had performed their roles so well. He was worried about comparisons from the audience but also considered this as motivation to complete the role well.
In response, Son Tung, born in 2006, expressed his admiration for his senior: "He considers me a premise, so I consider him an icon." The young actor said he also felt pressured to transform into a young Vien in a way that best blends with the thorny adult version that Ha Viet Dung had portrayed in previous films such as "Doc Dao".

Vien's mark through each stage
In the beginning, Son Tung successfully portrayed the image of an intelligent, thoughtful high school student who loves his friends and has innocent first feelings for his classmate Ngan.
When the film moves into adulthood, Ha Viet Dung takes on the role of Vien Lon, a successful, righteous man who still carries the echoes of his love life in his youth. The actor believes that this is "a very new type of role" compared to the characters he has played before.

The transition between the two stages is not only a change of actors but also an emotional journey, from sweet emotions to Vien's thoughts, responsibilities and unfinished love when he grows up.
The success and new developments of the movie
Contrary to the initial concerns of the actors, "1 millimeter away from you" is receiving great love from the audience. According to a report from VTV Ratings, the film held the top position in the Vietnamese film rankings on VTV during the week from October 27 to November 2, 2025.
Recent developments in the film focus on the troubles between Ngan's husband and a member of the old group of friends, pushing the characters into dramatic situations. Viewers are waiting for Ngan's decisions and Vien's role in the upcoming events. The film is broadcast at 8pm every Thursday and Friday on VTV3.
