The Sucker Punch star is set to play Johanna Mason, the cunning tribute from District 7 who helps Jennifer Lawrence's Katniss Everdeen upon her return to the Hunger Games arena.
"I'm super excited," Malone told E! Online. "It's going to be amazing."
Malone added that she has yet to meet the new director Francis Lawrence and is taking it "one step a time" in preparing for her role.
"I read the whole series over a weekend when I had a wisdom tooth out," Malone also shared.
"I was in bed looking for something to read and my little sister recommended it like a year and a half ago, so she was like, 'You have to read it! You have to read it!' And so I'm glad I finally did and I loved it."
Malone is currently filming Ten Cent Pistol in Los Angeles.
