"The Hunger Games: Mockingjay" has filled most of the roles for the two-part finale in the franchise, but add one more name to the list: Robert Knepper.

The movie's official Twitter revealed that the "Prison Break" star is joining the cast of "Mockingjay" parts 1 and 2 as Antonius: If you're a fan of the books, likely your first question is: "WHO?!" Antonius is not a character in the books; rather, he is a brand-new addition just for the movies. The Wrap reports he is President Snow's minister.

Director Francis Lawrence has been rounding out the cast in the last few months. New faces like Julianne Moore, Lily Rabe, and Patina Miller will join returning stars Jennifer Lawrence, Josh Hutcherson, and Liam Hemsworth.

"The Hunger Games: Mockingjay - Part 1" is set to fly into theaters November 2014, with "Part 2" due the following year.
