Fifty Shades Of Grey will be this year's (15) Oscars day number one movie in America, according to industry experts.

The erotic thriller, which stormed to the top of the box office over Valentine's Day weekend (13-15Feb15) with a record-breaking $85 million (£56.6 million) debut, is expected to stay at number one with an expected $30 million (£20 million)-plus second weekend haul.

That should be enough to outpace new movies Hot Tub Time MAChine 2, The Duff and Kevin Costner's MCFarland, Usa.

Fifty Shades has already grossed over $320 million (£213 million) globally since its release last week (13Feb15).
