It's not every day that you find an actual spoiler coming from a film director, but everything goes at the San Diego Comic Con. The participation of 'Hunger Games - Mockingjay Part 2' has brought about a possible spoiler for fans who have not yet read the books.

[SPOILERS COMING UP]

Director Francis Lawrence was answering a question from panel host Conan O'Brien, who asked for a non-spoilery summary of the film.

"I think you know this is where Katniss kind of gets back into action," the director said. "She was a bit sidelined in the last movie, and going through some of her own issues, but this time she's finally going after Coi -"

Lawrence paused before saying, "Uh, after Snow."

Book readers would know that he is referring to President Coin (played by Julianne Moore in the film), who initially presents herself as an ally. However, the character later turns out to have sinister plans and eventually causes an explosion that kills one of Katniss Everdeen's loved ones.

'Mockingjay 2' had a jaw-dropping presentation for the fans that attended Comic Con. In addition to the drummers who performed in Hall H, District 13 also had a special message.

The video also revealed Katniss Everdeen (Jennifer Lawrence) in a new red armor. The clip urged, "Stand with us" with the hashtag #Unite.

'Mockingjay Part 2' will be the final film in the 'Hunger Games' movie series, and would mean the last time that the cast and crew could attend Comic Con together. In celebration of that, Lawrence and her costars Josh Hutcherson and Liam Hemsworth made the best out of their panel.

Jennifer Lawrence also had the honor of meeting veteran actor Bill Murray, who was present to promote his film 'Rock the Kasbah.' The actress immediately went into fangirl mode when she found herself beside her idol.

'The Hunger Games: Mockingjay Part 2' will premiere on November 20, 2015.
