Kinky sex film Fifty Shades of Grey retains top spot at US and Canadian box office charts

LOS ANGELES (REUTERS) - Fifty Shades of Grey, an adaptation of the best-selling novel about a kinky relationship between a businessman and a college student, raked in another US$23.2 million (S$31.6 million) in ticket sales to lead United States and Canadian box office charts for a second week.

The film, which stars James Dornan and Dakota Johnson as the libidinous couple, again outpaced the No. 2 release, Kingsman: The Secret Service, which took in US$17.5 million from Friday through Sunday, according to studio estimates.

Third place on Oscar weekend, when Hollywood is buzzing with anticipation of Sunday's annual Academy Awards ceremony, again went to the family-friendly The SpongeBob Movie: Sponge Out of Water, based on the popular television show about a talking animated sponge. It sold US$15.5 million in tickets.

The three films replicated their standings from a week ago, and also outperformed a trio of new films that opened this week. Fifty Shades, a bona-fide box office bonanza, has already racked up US$410 million in global sales in less than two weeks.

Kingsman is an adaptation of a popular comic series starring Samuel L. Jackson and Colin Firth about a spy agency's training program and a global threat by a tech genius.
