The Hunger Games: Mockingjay Part 1 Trailer Officially Released Online

The final chapter of The Hunger Games begins here, and Katniss is going to war. 

This time three years ago, you would be forgiven for having never heard of Suzanne Collins' bestselling dystopian novels about a young girl who, after a moment of self-sacrifice, enters a fight-to-the-death competition and eventually becomes a national symbol of rebellion. Now, though, The Hunger Games saga is a pop-culture phenomenon that's grown far beyond its young adult roots, and the third film based on the series -- Mockingjay Part 1 -- is pretty much guaranteed to be one of the year's biggest movies. 

Sadly, we'll have to wait until 2015 to see how the entire saga really wraps up in Mockingjay Part 2, and we don't yet know where Part 1 will leave us hanging, but if this trailer is any indication, we're in for plenty of action, drama and heartbreak. Check it out.

The Hunger Games Mockingjay Part 1 hits theaters Nov. 21.
