The Hollywood film "Interstellar" has attracted more than 8 million viewers in South Korea, remaining at No. 1 in the local box-office rankings for the fourth week in a row, a market tracker said Monday.

The sci-fi epic by Christopher Nolan surpassed the 8 million milestone to reach 8.31 million viewers on Sunday, according to the data from the Korean Film Council (KOFIC).

It currently is the fifth most-viewed film in South Korean theaters this year, following Korean historical flick "Roaring Currents" (17.61 million), the animated Disney film "Frozen" (10.29 million), and "The Pirates" (8.66 million) and "Miss Granny" (8.65 million), both homegrown movies. 

Among non-Korean films, "Interstellar" is at No. 2 following "Frozen."

Interstellar features a team of space travelers who travel through a wormhole in search of a new habitable planet.

Starring Matthew McConaughey and Anne Hathaway as astronauts, it attracted 220,000 moviegoers on its Nov. 6 opening day and surpassed the 1 million mark on its third day and 3 million on its eighth day. (Yonhap)
