“Fifty Shades of Grey” sizzled at the weekend box office, setting new records for the highest-grossing Presidents Day holiday opener of all time and ranking among the biggest R-rated debuts in history. The erotic drama performed like a comicbook movie, albeit one with much naughtier costumes, picking up $81.7 million from 3,646 locations over the three-day period. That easily trumped the holiday’s previous record-holder, the 2010 debut of the romantic comedy “Valentine’s Day,” which kicked off with $56.3 million. Source, googlenews.
