Fifty Shades of Grey had a steep drop-off in its second week, dipping 72.7 percent to bring in $23.2 million, but it was still enough to stay on top of the weekend box office. The vanilla kink film led a tame box office, with the top three falling in line with the week prior: Kingsman: The Secret Service brought in $17.5 million, and The Spongebob Movie: Sponge Out of Water took in $15.5 million. New releases didn’t fare so well. Kevin Costner’s second white-savior film, McFarland, USA, brought in $11.3 million in its debut, whereas future high-school classic The DUFF brought in $11 million. Hot Tub Time Machine 2 tanked with $5.8 million. Too bad time machines aren’t real.
