Warner Bros. Pictures has announced that the theatrical teaser trailer for Harry Potter and the Order of the Phoenix will debut in theaters on November 17th. The trailer will be shown before the screening of Happy Feet. The trailer will then appear online in the coming weeks.

Harry Potter and the Order of the Phoenix arrives in conventional and IMAX theatres on July 13, 2007 and stars Daniel Radcliffe, Rupert Grint, Emma Watson, Imelda Staunton, George Harris and Helena Bonham Carter.

In the 5th installment in the franchise, Harry Potter is faced with the unreliability of the very government of the magical world and the impotence of the authorities at Hogwarts. Despite this (or perhaps because of it), he finds depth and strength in his friends, beyond what even he knew; boundless loyalty; and unbearable sacrifice.
