Evan RossIt's nesting season for the "Mockingjay."

Sure, "Hunger Games" fans still have three months to wait until the highly anticipated sequel, "Catching Fire," hits theaters, but casting is already ramping up on the third and fourth installments. The newest addition (per Lionsgate): "90210" alum Evan Ross (whom you may also recognize as Ashlee Simpson's boyfriend).

Evan joins "Mockingjay" as Messalla, one of the camera crew members filming propaganda for the Capitol. He's the assistant to director Cressida, who will be played by "Game of Thrones" actress Natalie Dormer.

Also added for the finale: Australian actress Stef Dawson, who will play Finnick's lady love Annie Cresta.

"The Hunger Games: Mockingjay - Part 1," starring Jennifer Lawrence, Josh Hutcherson and Liam Hemsworth, is scheduled for a November 21, 2014, release with "Mockingjay - Part 2" opening in theaters November 20, 2015.
