The Mockingjay lives!

The official 'The Hunger Games' Twitter feed released the final one-sheet poster for 'Mockingjay - Part 1,' which is set to hit theaters on Nov. 21.

We've seen glimpses of other character posters but this is the first we've seen of Jennifer Lawrence as Katniss Everdeen looking brave and fierce in the first of the two-part concluding chapter of the 'Hunger Games' trilogy.

In addition to the poster, the Twitter feed also announced that the final full trailer will debut on Monday, Sept. 15 at TheHungerGamesExclusive.com. But to whet the appetites of 'Hunger Games' fans everywhere, a 15-second video preview was released which you can see by clicking on the video above.

'Mockingjay - Part 1' co-stars Josh Hutcherson, Liam Hemsworth, Sam Clafin, Jena Malone, Phillip Seymour Hoffman, Jeffrey Wright and Julianne Moore.

The film's second part, 'Mockingjay - Part 2,' will be released on Nov. 20, 2015.
