Hint of Harry magic

The first trailer has been released for the next instalment of the Harry Potter and the Chamber of Secrets wizard saga.

But devotees of JK Rowling's creations still have to wait two months before the film actually opens.

In the film, Harry Potter, played by Daniel Radcliffe, is at his second year at Hogwarts School of Witchcraft and Wizardry.

In the trailers, viewers can catch a glimpse of the Great Hall, Dobby the house elf and actor Alan Rickman playing Professor Snape.

The film, the first sequel to last year's Harry Potter and The Philosopher's Stone, is scheduled to premiere in the US and the UK on November 15.

Dame Maggie Smith, John Cleese, Kenneth Branagh and Robbie Coltrane are also among the all-star cast.
