Associated Press: Will Smith’s caper “Focus” dethroned “Fifty Shades of Grey” at the box office, but the film’s modest $19.1 million opening still left questions about the drawing power of the once unstoppable star. According to studio estimates, Warner Bros.’ “Focus” easily topped all competitors on a weekend with little competition at the multiplexes. After two weeks atop the box office, “Fifty Shades” slid to fourth with an estimated $10.9 million for Universal Pictures.
