Warner Bros Pictures has dropped its plan to do a 3D conversion of Harry Potter and the Deathly Hallows - Part 1 in time for the film’s scheduled November 19 release.

Instead, the film will come out in a 2D version only, though in both conventional and IMAX theatres.

In a statement, the studio said the decision was made because ” we will not have a completed 3D version of the film within our release date window. Despite everyone’s best efforts, we were unable to convert the film in its entirety and meet the highest standards of quality. We do not want to disappoint fans who have long-anticipated the conclusion of this extraordinary journey, and to that end, we are releasing our film day-and-date on November 19, 2010 as planned.”

Harry Potter and the Deathly Hallows - Part 2, the final installment of the massively successful franchise, will still come out in 2D and 3D versions on July 15, 2011, the studio added.

Producer David Heyman said the decision reflects Warner’s “commitment” to the Harry Potter series and director (of Deathly Hallows parts one and two) David Yates said he supported the move.
