"Deadpool 2" dethroned three-week, box-office champion "Avengers: Infinity War" in South Korea, data showed Monday.

According to the computerized box-office tally from the Korean Film Council, the 20th Century Fox's R-rated superhero film "Deadpool 2" won the domestic box office, selling 1.352 million tickets from Friday to Sunday.

Disney and Marvel Studios' "Avengers: Infinity War" fell to No. 2 with 304,063 views after reigning the box office for three weeks.

Still, "Infinity War" remains strong despite losing its crown. In less than a month of release, the superhero film has attracted an audience of 10.689 million, becoming the second-highest grossing non-Korean film of all time in South Korea after "Avatar" seen by 13.6 million people in 2009.

Director Lee Chang-dong's "Burning" debuted at No. 3 on the chart with 220,717 admissions.

The mystery-thriller about the insecurity and anger of young people was premiered in competition at the 71st Cannes Film Festival. It earned the Fipresci International Critics' Prize for best film for its director and the independent Vulcan Award of the Technical Artist for its art director Shin Jeom-hee on Saturday (local time).

Coming in fourth was the newly released animated film "Peter Rabbit" seen by 102,397 cinemagoers, followed by "Love+Sling," a sports comedy starring Yoo Hae-jin that attracted 78,486 admissions.
