According to sources from Spotvnews, on the morning of January 15, the film crew of "The Sword: A Legend of the Red Wolf" officially announced the main cast including Park Bo Gum, Joo Won, Jung Jae Young, Lee Sun Bin and Kim Hyung Seo, quickly attracting the attention of the film industry and fans.
Previously, Star News Korea exclusively reported that Vietnamese actor Tran Thanh was considered to replace Cha Seung Won after this actor refused to participate in the project.
However, in the official announcement announced by director Kim Han Min, Tran Thanh's name did not appear in the cast list, leaving information related to his participation still uncertain.

Currently, a series of questions are being raised, related to Tran Thanh and the Korean film project.
Korean movie "The Sword: Legend of the Red Wolves" has not announced Tran Thanh's name? Or, was Tran Thanh just one of the options to replace Cha Seung Won? At the last minute, was Tran Thanh withdrawn from the film project or not chosen?
In the field of film, similar situations have happened many times, and it is not unusual. Many actors have been announced to participate in a project, but are not present at the last minute. Many reasons may occur, for example: schedule conflicts (artists are busy with another project so they ask to withdraw), contracts not reaching agreement between the two sides, script changes...
In this case, the majority of the audience regrets Tran Thanh.
The information that Tran Thanh participated in "Swordsman: Legend of the Red Wolves" once made fans excited. This will be an important milestone in Tran Thanh's career if he participates in an invested project with the participation of top Korean stars such as Park Bo Gum.
Park Bo Gum is known as the "national male god" of Korean cinema, possessing a brilliant career with a series of famous works such as "Reply 1988", "May hoa anh trang", "Ky su thanh xuan", "Khi cuoc doi cho ta qua quyt"... He always scores points thanks to his bright, radiant image and approachable demeanor.

Born in 1993, Park Bo Gum is the youngest child in a family of three sisters. From a young age, he showed talent for singing and playing the piano, once nurturing the dream of becoming a singer. At the age of 11, Park Bo Gum participated in auditions at many major entertainment companies such as SM, JYP, YG. However, SidusHQ - the actor management company - was the first place to contact and it was also here that he discovered his acting ability.
A major turning point in his career came to Park Bo Gum through the role of gentle, quiet Choi Taek in "Reply 1988". Success continued with the historical drama "May hoa anh trang", bringing his name to cover Asia and bringing many prestigious awards.
2025 marks a boom in Park Bo Gum's career with the main role in the Netflix movie "When Life Gives You a Mandarin" starring IU, setting an impressive rating record and IMDb score.
In the same year, he became the MC of The Seasons, won many awards at AAA 2025 and was appointed Korean Tourism Ambassador, affirming his position as a multi-talented star loved globally.
