Quoted from ANN:
The official Japanese website for the Haruhi Suzumiya anime franchise began streaming a one-minute promotional video for The Disappearance of Haruhi Suzumiya film on Friday, December 18. (The site “disappears” and deliberately posts a false “The page cannot be found” message in Japanese before the video is streamed.)
The film will open in Japan on February 6.
The Disappearance of Haruhi Suzumiya is the title of the fourth volume in Nagaru Tanigawa and Noizi Ito‘s original Haruhi Suzumiya light novel series about an eccentric, assertive girl who creates her own school club for her strange antics. The main story in this volume has yet to be animated. The first indications of animation plans for this light novel volume came in December 18, 2007, when the anime’s official website “disappeared” with a cryptic announcement of a new Haruhi Suzumiya project; December 18 is a reference to the pivotal date in the fourth volume. That 2007 announcement was also the first public indication that Yutaka Yamamoto (director of first and 12th Haruhi Suzumiya episodes, Lucky Star, Kannagi) was not going to direct the production of new Haruhi Suzumiya animation.
I still haven’t finished watching the season 1 but I’m looking forward for this movie.. ^_^
