'The Hunger Games: Mockingjay - Part 2' finally released a new official full-length trailer featuring new monsters as well as Jennifer Lawrence's Katniss Everdeen fight against the tyrannical Capitol. Liam Hemsworth is also speculated to be insecure towards his brother Chris\' big-screen success.

According to Entertainment.co.uk, Lionsgate debuted the long-awaited full-length trailer for the final half of the third installation in the 'Hunger Games' film series. Before its release, a teaser trailer had been aired out for fans of the trilogy.

In another article by Christian Today, the trailer featured footage of protagonist Katniss and her companions\' struggle against the Capitol and President Snow, played by Donald Sutherland. It showed numerous battle scenes, crumbling cities, soldiers in arms and what seemed to be human-lizard mutations rising from sewers.

The trailer promises an action-packed conclusion to the trilogy based on the young-adult books of the same name by author Suzanne Collins. Several characters rejoin Katniss on the big-screen including Josh Hutcherson's Peeta Mellark, Woody Harrelson's Haymitch Abernathy, Elizabeth Bank's Effie Trinket, and Liam Hemsworth's Gale Hawthorne.

The latter\'s strange reaction during the recent San Diego Comic Con tour made him the center of sibling rivalry rumors recently. According to The Daily Mail, Hemsworth momentarily snapped when a member of the press allegedly addressed him by his older brother\'s name.

He said, "You called me Chris? It's Liam. You called me Chris didn't you?" in a reportedly accusatory manner. It turned out that the interviewer's name was Chris and he was merely introducing himself. The 'Hunger Games: Mockingjay - Part 2' star quickly apologized and appeared awkward and flustered the entire time. This incident accelerated bouts of speculations concerning his purported jealousy on his brother\'s mainstream success.

'The Hunger Games: Mockingjay - Part 2' is a science-fiction adventure film set in the fictional dystopian world of Panem. It is set to be released on November 20, 2015.
