There's a brand new International trailer online for Harry Potter and the Half-Blood Prince and it carries with it some new footage and some darker, more concerning questions about the future for the characters.

Harry Potter and the Half-Blood Prince tells the story of our favourite wizard in training who hardly ever uses his powers in his sixth year at the Hogwarts school. There he discovers a book marked “This book is the property of the Half-Blood Prince” and he begins to learn more about Lord Voldemort.

The trailer looks pretty good, and I especially like the fact that Potter now has a bit more character about him and his sarcasm and wit seem to be growing with him. However this film does look like it's definitely going to be darker too.

Potter is growing up fast, and he's taking the films with him. Here's the trailer for Harry Potter and the Half-Blood Prince.
