Zack Snyder's first animated film, Legend of the Guardians, was just retitled from Guardians of Ga'Hoole yesterday, but the marketing push for the film is moving full-steam ahead.  The writer of the novels the film is based off of, Kathryn Lasky, posted on her website (via slashfilm) that a trailer would be attached to Tim Burton's Alice in Wonderland, which is releasing this Friday.

"My big news is about the Guardians movie! A trailer for it will be shown all across the country attached to Alice in Wonderland starting March fifth."

For just how long that trailer will be, the full synopsis, and a release date, hit the jump.

Brendon Connelly at SlashFilm also uncovered that the BBFC has a listing of the trailer, and that it runs 2 minutes, 15 seconds long and will arrive in 3D. This will be our first look at the film, which is quite exciting.

Lasky also couldn't help but weigh in on the name change.

"By the way, the movie will be called Legend of the Guardians. Hollywood is worried that nobody except you will know what Ga'Hoole means"

I still don't know what Ga'Hoole means, but perhaps they will explain it in the trailer. As promised, here is the official synopsis:

"The film follows Soren, a young owl enthralled by his father's epic stories of the Guardians of Ga'Hoole, a mythic band of winged warriors who had fought a great battle to save all of owlkind from the evil Pure Ones. While Soren dreams of someday joining his heroes, his older brother, Kludd, scoffs at the notion, and yearns to hunt, fly and steal his father's favor from his younger sibling. But Kludd's jealousy has terrible consequences-causing both owlets to fall from their treetop home and right into the talons of the Pure Ones. Now it is up to Soren to make a daring escape with the help of other brave young owls. Together they soar across the sea and through the mist to find the Great Tree, home of the legendary Guardians of Ga'Hoole-Soren's only hope of defeating the Pure Ones and saving the owl kingdoms."

Look for Legend of the Guardians to release wide by Warner Bros. on Sept. 24, 2010.
