Even though in Europe we had to wait till Monday to see the new [The Hunger Games: Mockingjay - Part 1](movie:446261) trailer, it's here and it is amazing.
The first thing we see is the plane landing in District 13. Inside that plane Plutarch and Alma Coin are having a conversation.
"Listen to me. No one can do this but her."
"She won't be able to handle it... The games destroyed her."
"We need to unite these people out there. She is the face of rebellion. They will follow her."
Meanwhile we see Katniss walking in a hospital and people start staring at her. My opinion is that they are in District 13 with people who survived the attacks in Districts 12 and 13. Afterwards we see President Snow in Capitol saying "Any association of the Mockingjay symbol is forbidden".
Seconds before the Mockinjay symbol pops up a boy patient asks Katniss.
"Are you fighting Katniss? Are you here to fight with us?"
"I am. I will"
We all know Katniss didn't want to be the symbol of rebellion or lead anyonein The Hunger Games and in Catching Fire. However in this scene she seems decided to fight the Capitol.
In this trailer there are many things that show that war is coming. Firstly, Peacekeepers are at shooting people and people are running for their lives. Secondly, Gale is causing an explosion. And last but not least the two dialogues shown in the trailer.
Now three things you may have ignored while watching it:
1) We get to see how District 13 looks like at the very begging.
2) The revolution might be televised like the Hunger Games
3) We get to see a new character and if I recognized her well from IMDb she is Cressida played by Natalie Dormer.
