Conan O'Brien was at the moderator's mic for the very last Hunger Games panel at Comic-Con.

The panel kicked off with drummers dressed in white outfits banging away at drums both on the stage and out on the Hall H floor at the San Diego Convention Center, followed by a short clip of hundreds of similarly dressed soldiers rallying behind a red-clad Katniss Everdeen. Following that, Conan O'Brien bounded onstage and told the crowd that he had his pick of panels to moderate and wanted this one.

The talk show host then brought out stars Jennifer Lawrence (Katniss), Liam Hemsworth (Gale), Josh Hutcherson (Peeta) and Willow Shields (Prim), plus director Francis Lawrence and producer Nina Jacobsen for one last Hunger Games panel at Comic-Con before the series bids farewell with Mockingjay Part 2.

Jacobsen said about bringing the story to a conclusion: "I think it's been emotional for all us...we want to deliver on the emotion and the politics of it, all of the things that Suzanne had to say about our culture. So it's been a combination of trying to nail it and make sure it's completely satisfying, while enjoying the time that we have together."

Francis Lawrence added: "This film was the most satisfying and gratifying for me because it ends the story...I'm really pleased with the film and how it ends." Jacobsen remarked that she wished there was seven or eight books, leading Conan to joke that he's "hastily" written a new script in which he is prominently featured.

The lights were then dimmed and the first full trailer for the movie was unveiled. From the looks of it, the studio, producers and stars have left everything out on the field for the finale of the series, which has a hugely expanded scope as Katniss and the revolutionaries march on the capital and must navigate President Snow's (Donald Sutherland) bizarre new series of traps that Finnick calls "the 76th annual Hunger Games." Exploding buildings, huge cascading walls of oil, lots of fire and shots of the capital in ruins emphasized that Francis Lawrence has made this final entry into an all-out battle movie.

The trailer not only provided a glimpse of full-on open warfare in the streets of the capital, but dramatic and emotional moments for all the characters, as well (although Liam Hemsworth deadpanned at one point later, "Peeta and Gale have a really emotional scene together and there might be a kiss involved."). The trailer -- which won't be out for a few weeks yet -- ended with Katniss proclaiming, "Turn your weapons to the capital. Turn your weapons to Snow."

The gravitas of the trailer was balanced by the more lightweight tone of the panel, which came complete with some new "Jenniferisms," as when the Oscar-winning actress said in response to one question, "What I have to say is really interesting in my head but I'm not going to be able to get it out."

It wasn't exactly a panel full of news -- what is there left to report? -- but it did provide the fans and cast to share a last Comic-Con encounter together before The Hunger Games come to a close this November. Josh Hutcherson offered up a final, heartfelt thanks to the fans, while Jennifer Lawrence said, "These movies changed my life and I don't think I'll ever say goodbye. Katniss is a part of me."
