10 Terrible Movies That Still Managed To Break The Box Office

Rotten Tomatoes Score: 25%

EL James is not, at heart or in practice, a writer, but a fanfiction blogger who woke up one day to find the entire world was reading her toilet Tweets. Written on a Blackberry phone and inspired by the Twilight series, James' best-selling Fifty Shades of Grey was on a collision course with Hollywood as soon as book sales passed the one-million mark.

The source material is unforgivably bad, but here's the thing - even if the filmmakers had been able to beef up the characters, the dialogue and the plot, it's the sex that got your mum and your nan and whoever else so psyched for the book in the first place (no matter what they tell you). Even with an 18 certificate, this mainstream studio release was simply never going to be able to go all the way (or even, really, halfway).

Thus the $40 million production, directed by Sam Taylor-Johnson and starring Dakota Johnson and Jamie Dornan, sated nobody's desires. But that didn't stop audiences piling into the cinema in their droves, armed with all manner of paraphernalia. Fifty Shades of Grey ultimately made $569 million in ticket sales, a staggering sum for an adult-only flick, which has made it the second most successful 18-rated film of all time, after Mel Gibson's The Passion of the Christ.
