Park Jihoon Expands His Career From Idol Star to Box Office Actor With Breakthrough Historical Role

Park Jihoon is no longer being discussed only as a former idol or successful solo artist. With his latest film performance, he is firmly establishing himself as a bankable actor on the big screen.

His transformation has become one of the most talked-about career evolutions in recent years, as he moves from stage to streaming hits and now to a major theatrical success.

First Historical Film, A Defining Performance

Park Jihoon recently made his first appearance in a historical film through The Man Who Lives With the King, a Lunar New Year box office hit that surpassed four million moviegoers.

Despite it being his first attempt at the genre, his portrayal of Danjong and the emotional journey of Lee Hong-wi after his fall from the throne stood out for its restraint and depth.

Rather than relying on heavy dialogue or action scenes, he carried the character through:

• controlled facial expressions
• layered eye acting
• detailed reaction performances

His emotional exchanges with Yoo Hae-jin built the film’s core narrative, helping audiences remain immersed throughout the story.

The Role That Changed Everything: Weak Hero Class 1

The foundation for this recognition was laid earlier through the Wavve series Weak Hero Class 1.

As Yeon Si-eun, a student who evolves from a victim of school violence into a calculating fighter, Park Jihoon delivered a performance that surprised both viewers and critics. His ability to move between vulnerability, rage, and grief created what many called the “Weak Hero syndrome.”

The drama later expanded its global reach after moving platforms and releasing a second season, further strengthening his reputation as a serious actor.

A Career Built on Steady Growth

His journey began long before his idol debut.

Starting as a child actor, he rose to national fame through Produce 101 Season 2, where his “Save you in my heart” catchphrase became a cultural phenomenon and led to his selection as a member of Wanna One.

After the group’s activities ended, he successfully balanced two careers:

• releasing solo albums and winning music show trophies
• steadily building a diverse acting filmography

From Flower Crew: Joseon Marriage Agency and Love Revolution to At a Distance, Spring Is Green and Fantasy Sonata, each project added to his range.

Box Office Power and the Next Challenge

With a theatrical hit now added to his résumé, Park Jihoon has proven his ability to draw audiences beyond the idol fanbase.

His next project, the TVING original series The Legendary Cook Soldier, will show yet another transformation as he plays a young man who enlists in the military and grows into a legendary cook.

The role is expected to highlight:

• his comedic timing
• character-driven storytelling
• ensemble chemistry

From “Save You in My Heart” to Leading Actor

Park Jihoon’s career has become a rare example of an idol successfully transitioning into a respected actor through consistent project selection and visible improvement.

With both box office credibility and a globally recognized drama under his belt, his next move is no longer a question of possibility but of how far his acting spectrum will expand.
