The Harry Potter trio are back to save Hogwarts from dark forces in the eagerly anticipated sixth film in the series.

A year after the last Potter film, Harry Potter And The Order Of The Phoenix, JK Rowling's creation is back in British cinemas in November with Harry Potter And The Half Blood Prince.

In this sneak peek of the new film, the young stars are looking more grown-up than ever, seven years after they leaped to fame in the first movie, Harry Potter And The Philosopher's Stone.

Back together: Harry Potter (Daniel Radcliffe), Hermione Granger (Emma Watson) and Ron Weasley (Rupert Grint) are back as the magic trio in Harry Potter And The Half Blood Prince

The leading trio, Daniel Radcliffe (Harry Potter), Ron Weasley (Rupert Grint) and Hermione Granger (Emma Watson) are now 18, 19 and 18 respectively.

When they started out in 2001, they were just pre-teens and fans have watched them grow up on screen.

Boy wizard Harry is steadily evolving into a 'man wizard' as he expands his powers with the assistance of a mysterious book, entitled 'Property Of The Half-Blood Prince'.

As well as battling evil, Harry finds himself falling for Ginny (Bonnie Wright), the little sister of best pal Ron.

Harry previously enjoyed a kiss with Cho Chang (Katie Leung) in the Harry Potter And The Goblet Of Fire in 2005.

When asked if Harry will lock lips with Ginny, director David Yates said: 'They're about to kiss. Then the bloody Death Eaters turn up and cause all sorts of anarchy.'

Evil: Harry's nemesis Draco Malfoy (Tom Felton) moves even closer to the dark side

Harry isn't the only one with the love plot - Ron find himself subject to the attentions of Lavender Brown, much to the disdain of jealous Hermione.

The focus of the latest film is the dark evolution of Harry's blond rival Draco Malfoy (Tom Felton).

In the movie, Harry is 16 and is deeply suspicious of Draco and teams up with Dumbledore to keep Hogwarts protected from evil.
