The final installment of "The Hunger Games" trilogy is going to arrive in November, and it seems that the chapter is ready to shake fans up.

For book readers, they already know what's in store, but if you watched the trailer without taking a crack at Suzanne Collins's words, there are several spoilers from the trailer:

As Movie Pilot noted, here are some of them:

1) The marriage of Finnick and Annie, and their wedding ceremony will be attended by a crowd that includes Plutarch, Effie, Haymitch, and even President Coin. Unfortunately, as Katniss narrated, "Nothing good is safe while Snow's alive."

2) The ever fashionable Effie will help Katniss prepare in what seems to be the execution scene for President Snow, with Katniss donning rebel-like clothes that could mean she's ready for a fight.

3) An off-book scene also took place, with Katniss and Gale seemingly attending a sort of rally.

4) Katniss's speech to the masses, addressing the corrupt and evil ways of President Snow, telling people that "he corrupts everyone and everything" and that "he turns the best of us against each other." The last line being a bit mysterious.

5) Then, as the trailer finishes, there is still another line that killed all the fans: "Ladies and Gentlemen, welcome to the 76th Hunger Games."

While the trailer has created a frenzy for "The Hunger Games" fans, an even bigger movement is taking place in social media websites for the posters that appeared all over the world, telling citizens to unite in a three-finger salute that is known to be for Katniss.

Photos of the poster began appearing on social media, with fans from all over the world making their own salute for the Mockingjay.

The "Unite" posters for "Mockingjay Part 2" showed the iconic hand sign with a District 13 logo next to it.

The sign, according to Katniss's narration from the first book, is an old gesture in District 12. She said, "It is an old and rarely used gesture of our district, occasionally seen at funerals. It means thanks, it means admiration, it means good-bye to someone you love."

This is not the first time that Lionsgate made propaganda posters to promote the film. Last year, they also promoted the film without any use of "The Hunger Games" or "Mockingjay" logos, preferring to shock the world with photos of dismal conditions from children from the poorer Districts, based on the books.

What do you think of Lionsgate's PR technique?
