Harry Potter & The Half Blood Prince - Harry looks scared... A new trailer for the sixth Harry Potter movie has appeared online. The two-minute trailer features a sneak-peek at loads of stunning set pieces, not to mention some classic Ron Weasley comedy moments.

If anything, the trailer for the new Harry Potter movie shows exactly how dark director David Yates is willing to take the series.

From a London-based Death Eater attack (watch as the Millenium Bridge gets all twisted up) to Harry's worrying trip to a seaside-rockface with Dumbledore, the pivotal moments of The Half Blood Prince look like they will be as harrowing as when they were when first read in JK Rowling's 2005 book. 

Check out the trailer and images below.
