When Lucy Gray (Rachel Zegler) is selected for the 10th Hunger Games, she gives a little bow, mirroring the one Katniss (Jennifer Lawrence) gives in 2012's "The Hunger Games" during an evaluation.
This is different from the books, where Lucy Gray takes her fellow District 12 tribute's hand and the pair bow together.
"It was actually an improvised moment," director Francis Lawrence told Business Insider. "I came up with the idea on the day for her to do it, to do the curtsy bow."
"We were always looking at any given moment, through the process of making this film, of nodding to the origins of certain things," Lawrence said, adding, "I thought it could be really interesting if Katniss had done it because she's heard that, generations ago, there was a woman who sort of irreverently did this curtsy bow after this performance on stage when she's dragged off to the games. I just liked the idea that Lucy Gray was actually the first one to do it and that there was a history of it."
He added: "It was an improvised thing on the day, wasn't even talked about ahead of time. I think in early takes she wasn't doing it and then I just came up with the idea. I knew the fans would really like it and I thought Rachel would love the idea."
