The '50 Shades of Grey' trilogy, the most notorious novels of the 21st century, is headed to the big screen, with a release date set for Valentine's Day 2015.

Filming is almost wrapped up and its stars, Jamie Dornan and Dakota Johnson, are purposely keeping a low profile so that few details of the movie become public.

'Grey's' first trailer, released yesterday, gives the quick look at what most expect to be a box office bonanza.
