Coming soon: Darkest Harry Potter film
The fairytale is definitely over as the scenes, from the trailer of the first part of the adaptation of the final book, look more like a disturbing thriller than a children's fantasy tale, Daily Mail online reported.
Daniel Radcliffe, Emma Watson and Rupert Grint all star in what is being hailed as the darkest Potter film yet.
The images in the trailer are from both parts of the final story. They show Hermione, played by Watson summoning up a spell in a forest with the half naked body lying on the floor behind her.
There are also pictures of Ralph Fiennes as arch-villain Lord Voldemort doing battle with Harry as well as the usual pyrotechnics including a massive explosion.
Observers say the films have got darker and more gothic as time has gone on and as the child stars have turned into adults.
Harry Potter And The Deathly Hallows Part 1 comes to British screens in November, with Part 2 following in July next year.
The films do not yet have a certificate and there are rumours the movie censors will have a tough task deciding what rating to give.
But there are fears among some fans that it could risk alienating parents if the action is too far removed from the family friendly feel of earlier movies.
The film centres around Harry, Ron and Hermione's attempts to find and destroy the Horcruxses, the secret to Voldemort's immortality and destruction.
The action also sees Voldemort's death eaters seize control of the Ministry of Magic and then hunt for Harry Potter.
