The controversial fantasy romance "Fifty Shades of Grey" lands ahead of "Kingsman: The Secret Service" and the previous week's leader "Spongebob Squarepants: Sponge Out of Water" at the worldwide box-office for the weekend ending February 15.

The Sam Taylor-Wood adaptation of E. L. James' bestseller made back its budget six times over, a $239m take on $40m worth of funding, according to data supplied by Rentrak and BoxOfficeMojo.

With forecasts predicting a theatrical tally that exceeds $300m, "Fifty Shades of Grey" is well on the way to becoming one of the top five R-rated movies at the international box office.

In second place, the Colin Firth and Taron Egerton action comedy "Kingsman: The Secret Service" provided another book-to-film adaptation, and proof that director Matthew Vaughan's still got the magic touch after "Kick-Ass" and "X-Men: First Class."

Xu Jinglei's Czech-based Chinese romance "Somewhere Only We Know" also enjoyed success with its mixture of Mandarin and English dialogue and Prague's scenic backrop.

1. "Fifty Shades of Grey"
2. "Kingsman: The Secret Service"
