UPDATE: 2/16 11 AM PST:Deadline is now reporting that, by the end of the four-day Presidents Day holiday weekend, Fifty Shades of Grey will have earned $94.4 million at the domestic box office, and $172 million overseas for a worldwide haul of $266.4 million worldwide. This sets a record for the highest international opening weekend in the month of February. Its Wednesday-Sunday international opening of $156 million is the second highest ever for Universal, behind the $160.3 million take for 2013's Fast & Furious 6. On Saturday, Valentine's Day, Fifty Shades of Grey earned $55 million internationally, making it the highest-grossing day overseas in Universal history.

Original Story:Fifty Shades of Grey is already a big hit in the U.S., taking in $81.6 million during its opening weekend, and now the adaptation of E.L. James novel is a hit overseas as well, earning over $240 million worldwide. The $158 million international gross is a new box office record for an R-rated movie, breaking the former record set by The Matrix Revolutions ($117 million). The adaptation, which was made for just $40 million, was the #1 movie in 55 of the 58 international markets it debuted in over the weekend.

Over 60% of all international moviegoers preferred Fifty Shades of Grey over other competing movies such as Kingsman: The Secret Service, which was the top movie in Singapore, Hong Kong and Thailand. Universal still has five more international markets to open Fifty Shades of Grey in, including Korea on February 26 and the United Arab Emeriates on March 5. What remains to be seen is how the adaptation will fare both domestically and internationally throughout the rest of February and into March, when highly-anticipated movies such as Chappie (March 6) and The Divergent Series: Insurgent (March 20) debut.
