Here ye, here ye! The next Hunger Games are about to commence.

With filming of the franchise’s third installment set to kick off in September, Lionsgate has been hastily rounding out the cast for the The Hunger Games: Mockingjay Part 1 & 2, the two-part feature finale to the blockbuster adaption of the best-selling Suzanne Collins trilogy.

Here are the latest to join the Games: [Warning: Some spoilers ahead]

Natalie Dormer
… will star as Cressida, the filmmaker who collects footage of Katniss’ rebellion against the corrupt Capitol. Game of Thrones fans will know this British actress as Margaery Tyrell, the bride-to-be of the brutal King Joffrey. Dormer had a role on Showtime’s period drama, The Tudors, and in Captain America: The First Avenger.

Evan Ross
… will star as Messalla, the Capitol-bred assistant to Cressida. You might know his name one of three ways: as an alum of teen soap 90210, as the son legendary singer Diana Ross, or as Ashlee Simpson’s boyfriend. Ross has a number of roles under his belt, from Jeff, Who Lives at Home, to ATL, to The Family Tree.

Stef Dawson
… will star as Annie Cresta, a District 4 victor who holds the heart of Panem’s fawned-over hunk Finnick Odair (Sam Claflin). The Australian actress is mostly unknown, having credits in a few short films and indies, and set to appear in upcoming horror film 13 Girls.

Meanwhile, Julianne Moore has been rumored for last notable roles – President Alma Coin, the District 13 president who leads the people of Panem in the rebellion against the Capitol.

The newcomers join returning principals Jennifer Lawrence (Katniss Everdeen), Josh Hutcherson (Peeta Mellark), Liam Hemsworth (Gale Hawthorne), Elizabeth Banks (Effie Trinket), and Woody Harrelson (Haymitch Abernathy), among others.

The franchise’s second film, The Hunger Games: Catching Fire, hits theaters Nov. 22. The Hunger Games: Mockingjay will be split into two movies, with the first opening on Nov. 21, 2014, and the second on Nov. 20, 2015.
