With the summer movie season winding down, some are already looking ahead to see what this fall has to offer. One movie that could make some big waves at the box office is Storks, hitting theaters on September 23, featuring an incredible voice cast that includes Andy Samberg, Jennifer Aniston, Kelsey Grammer, Ty Burrell, Key & Peele and rising star Katie Crown. Today we have the fourth trailer for this animated adventure, which shows how the Storks' plight has evolved over the years.

Storks deliver babies... or at least they used to. Now they deliver packages for global internet giant Cornerstore.com. Junior (Andy Samberg), 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 (Katie Crown), 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.

Back in April, Warner Bros. gave their upcoming family adventure Storks a September 23, 2016 release date. Since we still have several months left until this movie hits the big screen, there is still plenty of time for new trailers and clips to debut. The supporting voice cast is rounded out by Danny Trejo, Stephan Kramer Glickman and Anton Starkman. Nick Stoller wrote the screenplay and directs alongside Doug Sweetland.

The Lego Movie directors Phil Lord and Chris Miller are executive producing alongside Glenn Ficarra, John Requa and Jared Stern. Storks will be the first feature film developed under the new Warner Animation Group, along with the first foray into animation for filmmaker Nick Stoller. He has previously directed live-action comedy movies such as Neighbors, The Five-Year Engagement and Forgetting Sarah Marshall.

Storks will be going up against Sony's remake of The Magnificent Seven on September 23, along with The Queen of Katwe, The Lovers and the Despot and The Dressmaker in limited release. We'll have to wait and see if these lovable Storks can out-gun The Magnificient Seven when they both square off at the box office. Until then, take a look at the new trailer for Storks below courtesy of Warner Bros., and stay tuned for more on this animated comedy.
