Actor Park Seo Joon’s 7 Kg Weight Loss For “Concrete Utopia” Had One Major Side Effect

Joining actors Park Bo Young and Lee Byung Hun, Park Seo Joon‘s latest project is the disaster thriller Concrete Utopia. To fully get into the character of Min Seong, he underwent a bit of a transformation.

During an interview with The Korea Times, the actor revealed he lost 7 kg (roughly 15 lbs) for the role. However, it came with an unexpected side effect.

Despite the movie taking place in winter, following an earthquake, the cast had to film in the summer heat. Park Seo Joon revealed, “We had to pretend it was winter in the middle of summer.”

Wearing heavy winter clothes in the summer was far from comfortable for Park Seo Joon and quickly became dangerous. He confessed, “There were times when I felt dizzy because I lost about seven kilograms for the part. I had to explore certain emotions that I have never experienced before.”

Park Seo Joon’s slimmer figure may have defined his abs and arm muscles but made filming even more challenging. Fortunately, the actor was able to avoid serious problems such as heat stroke and injuries from fainting.
