Netflix’s ‘Mousetrap’ Breaks Into Top 10 in 49 Countries as Ryu Jun-yeol’s Dual Role Draws Attention

Netflix has another Korean thriller quickly gaining international attention.

Just four days after its release, “Mousetrap” climbed to No. 6 in FlixPatrol’s global TV ranking and entered the Top 10 in 49 countries.

Ryu Jun-yeol Takes on Two Roles

The psychological mystery thriller stars Ryu Jun-yeol as Moon-jae, a reclusive novelist whose identity, money and life are suddenly taken from him.

Behind the nightmare is a mysterious figure known as “The Rat”, forcing Moon-jae into a desperate fight to prove who he really is.

The series is attracting particular attention for Ryu’s first dual-role performance, portraying both sides of the increasingly complicated identity mystery.

Top 10 in 49 Countries

According to FlixPatrol data reported on September 1, “Mousetrap” reached No. 6 globally among TV shows only four days after premiering on Netflix on August 28.

The series entered the Top 10 in 49 countries, including South Korea, France, India, Singapore, Malaysia, Thailand, Saudi Arabia and the United Arab Emirates.

A Korean Folktale Reimagined as a Modern Thriller

“Mousetrap” is based on the Korean webtoon “Field Mouse”, which itself draws inspiration from an old Korean folktale about a rat that assumes a person's identity.

Netflix’s modern version transforms that disturbing idea into a story about identity theft, deception and the increasingly blurred line between the real person and the imposter.

A Strong Cast Behind the Mystery

Ryu Jun-yeol is joined by veteran actor Sul Kyung-gu as Noja, a ruthless loan shark who becomes an unlikely ally in the search for the Rat.

Lee Kyoo-hyung plays detective Sun-yong, who is also pursuing the truth behind the mysterious case.

The 10-episode series is directed by Kim Hong-sun, whose previous work includes “Money Heist: Korea – Joint Economic Area” and “Dear Hongrang.”

With its unusual Korean folklore inspiration, identity mystery and high-profile cast, “Mousetrap” is quickly emerging as one of Netflix’s Korean titles to watch this fall.
