Christopher Nolan‘s “Interstellar” is proving to be a juggernaut at the foreign box office.

The space epic starring Matthew McConaughey brought in $74 million from 64 overseas markets this weekend, raising its international total for distributor Warner Bros. to $329 million. With its $120 million haul from North America, where Paramount Pictures is handling the film, its global total is at nearly $450 million in three weeks.

“Interstellar” brought in $30.6 million in its second weekend in China, where its total is now over $82 million. It also generated $10.4 million from Korea, where it stayed No. 1 for the third consecutive weekend.
