We've been waiting in anticipation for months but finally the wait is over and we get to see Katniss Everdeen, played by Jennifer Lawrence, back in her full arrow-slinging glory in the official full-length trailer for The Hunger Games: Mockingjay Part 1.

For anyone who needs catching up, Katniss is now leading the rebellion and has become the figurehead in the fight against the Capitol.

In the trailer, there's a lot of action, so we're expecting lots of fighting, heartache and many battles between the Capitol and the revolutionaries from the various Districts.

We also get to see President Snow utter the chilling words to Katniss "it's the things we love most that destroy us".

There's also an incredible blink-and-you'll-miss it moment where we get to see Effie Trinket (played by the brilliant Elizabeth Banks) without her massive pink hair and in much simpler clothes. A distinct change from her usual outlandish costumes. Could it be that she's switched to help those who live outside of the Capitol and has joined the revolution?

We also get to see Peeta Mellark, who appears to currently be on the side of The Capitol, imploring the fighters to lay down their weapons. Katniss, clearly thinking that he was dead, is happy to see that he's OK, although clearly there'll be trouble ahead.

Also starring in this film is Julianne Moore as President Alma Coin, Sam Claflin as Finnick Odair, Liam Hemsworth as Katniss' childhood and district friend Gale Hawthorne, and the late Philip Seymour Hoffman as Plutarch Heavensbee.

So far, we've seen some incredible teaser trailers for the upcoming movie, with President Snow and Peeta in a propaganda video but this is the first time we've been able to see Katniss in full flow.

Hello goosebumps.
