Update: This rumor turned out to be false, as the three main cast did not make an appearance at SDCC.
The first trailer for The Hunger Games: Mockingjay Part 1 is set to debut today at the Samsung Galaxy Experience at the Hard Rock Hotel outside San Diego Comic Con this morning and while Lionsgate previously announced the cast members that will be on site to sign posters at their convention booth, they have remained tight lipped about who will be on hand to present the trailer today.
Speculation has run rampant over who will be making the debut, with some fans believing that the “big three” would make a surprise appearance to present what the entire fandom has been anticipating for months. Rumors have been swirling even more ferociously this morning with security at the line claiming that Jennifer Lawrence, Josh Hutcherson, and Liam Hemsworth will indeed be the talent appearing for the big reveal.
