It's only been on general release since yesterday but Fifty Shades of Grey is already box office gold.

The final tally on the movie's global weekend take will not be available until Monday but estimates in America alone have suggested that the box office takings could be around $85 million for its first four days of release.

Midnight screenings in the US took $8.6 million alone and the movie, which has been described as "more M&S than S&M", is expected to do very brisk business today, Valentine's Day.
