"These are dark times, there is no denying." So begins the newly released promotional trailer for the upcoming 3D sequel "Harry Potter and the Deathly Hallows: Part I."

The British boy wizard once again will work his magic on movie audiences when "Deathly Hallows" hits theaters in November. A look at the trailer, released Wednesday by Warner Bros. Pictures, shows as much action as ever when multiple Harrys -- at least six of them -- are conjured up to help him battle his nemesis Lord Voldemort.

Harry's friends, Hermione Granger and Ron Weasley, also join the fight against the dark lord who now has control over the Ministry of Magic. But as Voldemort's powers grow, the bond among the three Hogwarts schoolmates becomes frayed, and Ron and Harry come to blows.

Will they remain friends and defeat Voldemort? The answer remains in doubt because, as the trailer tells audiences, "only one can live" when it comes to the battle between evil Voldemort and good Harry.

The Potter movies, based on the best-selling novels by author J.K. Rowling, have raked in billions of dollars at the worldwide box office. Rowling's final book, "Harry Potter and the Deathly Hallows," was split into two films, with the second installment hitting theaters next July.
