Animated adventures have been big at the box office over the past decade, but it's a genre usually dominated by Pixar, Disney and DreamWorks. Though Warner Bros. has also had its fare share of CG hits, the studio returns this fall with its most ambitious comedy yet! Storks is in theaters this September. Today, we have the third exciting trailer along with the official one-sheet poster, which asks you to 'Find your flock!'

Storks arrives in 3D and 2D in select theaters on September 23. Nicholas Stoller, best known for such raunchy comedies as Forgetting Sarah Marshall, Get Him to the Greek, Neighbors and this summer's Neighbors 2: Sorority Rising, takes his first stab at making a family movie everyone can enjoy. He directs alongside Doug Sweetland. The duo are working from a script Nicholas Stoller wrote himself. Stoller is also producing alongside Brad Lewis. Executive Producers include 21 Jump Street directing duo Phil Lord and Christopher Miller, who are joined by Glenn Ficarra, John Requa and Jared Stern.

Leading the ensemble voice cast are Andy Samberg and Kelsey Grammer. They are joined by a vast array of talent from the world of film and television including Katie Crown, Keegan-Michael Key, Jordan Peele, Danny Trejo, and Ty Burrell. Iconic actress Jennifer Aniston finally makes a return to the animated world with her first voice role since taking on the 1999 classic Iron Giant. There will also be a few surprises to discover along the way.

Storks imagines what happened to the folklore of yesteryear in an age when social media allows everyone in the delivery room. These once proud birds used to deliver babies. Now, they deliver packages for a global internet retail giant. Junior, the company's top delivery stork, is about to be promoted when he accidentally activates the Baby Making Machine, producing an adorable and wholly unauthorized baby girl.

Desperate to deliver this bundle of trouble before the boss gets wise, Junior and his friend Tulip, the only human on Stork Mountain, race to make their first-ever baby drop, in a wild and revealing journey that could make more than one family whole and restore the storks' true mission in the world. Along with the new trailer and poster, Warner Bros. is also introducing a few new treats for fans to get excited about the movie.

The studio has officially launched the Storks company site, which takes audiences inside Stork mountain. Now you can get an inside look at the inner workings of the Cornerstor at www.InsideStorkMountain.com. There is also the exciting Stork Delivery Dash game. Wondering if you have what it takes to soar to the top of Stork Mountain? Storks Delivery Dash lets you join the exciting world of winged delivery service. Fly through the neighborhood and deliver packages by air with flawless timing and stork-like precision. And remember to watch out for obstacles! Cornerstone relies on dependability! But before you get all wrapped up in that fun, be sure to check out the new poster and trailer, which promises to be a lot of fun on its own! In theaters only this fall.
