If you're not a Stephen King fan, the entire concept of 'The Dark Tower' might be going over your head a little but don't worry, the new trailer is here to explain it all. Sort of.

This film adaptation of King's work has been long in the making and while condensing it down to a single film was always going to be challenging, it looks like Sony are trying their hardest for it to appeal to old fans and new.

Here's the official synopsis:

"There are other worlds than these. Stephen King’s The Dark Tower, the ambitious and expansive story from one of the world’s most celebrated authors, makes its launch to the big screen. The last Gunslinger, Roland Deschain (Idris Elba), has been locked in an eternal battle with Walter O’Dim, also known as the Man in Black (Matthew McConaughey), determined to prevent him from toppling the Dark Tower, which holds the universe together. With the fate of the worlds at stake, good and evil will collide in the ultimate battle as only Roland can defend the Tower from the Man in Black."

'The Dark Tower' is set for release in Irish cinemas on August 18th.
