‘Fifty Shades of Grey’ Leads Weekend Box Office, Stirring Reflection on Sex Films

LOS ANGELES — Moviegoers turned out en masse to see the sadomasochistic love story “Fifty Shades of Grey” over the Presidents’ Day weekend, delivering a triumph for Universal Pictures and potentially altering Hollywood’s approach to sex.

“Fifty Shades of Grey,” capitalizing on the fall of Valentine’s Day on a Saturday, will take in about $90.7 million between Thursday night and Monday, according to Rentrak, which compiles ticketing data. The movie, which cost $40 million, attracted an audience that was 68 percent female, Universal said.

The film, directed by Sam Taylor-Johnson and based on the erotic novel by E. L. James, played in 3,646 theaters in North America, the largest release in history for an R-rated movie, according to Nick Carpou, Universal’s president of domestic distribution. “Theater owners added screens in response to a clamor from their patrons,” Mr. Carpou said on Sunday.

Female fans of the best-selling book — apparently dragging along a lot of reluctant husbands and boyfriends to theaters — created a wave of interest that pushed past reviewers, who gave the film terrible notices. Also drowned out were those calling for a boycott, among them the feminist group Stop Porn Culture, several domestic abuse organizations and the Roman Catholic archbishop of Cincinnati.

Universal also advertised the film during the Super Bowl.

Phil Contrino, chief analyst at BoxOffice.com, said on Sunday that “Fifty Shades of Grey” was on pace to take in $500 million worldwide without batting an eye. He called that a ticket-selling achievement “that’s sure to shake up the definition of what a blockbuster can look like.”
