Body double Loren Peta played the young Rachael (in costume, makeup, and with dotted face) and performed on set with Ford and Jared Leto. She was directed by Denis Villeneuve, with Young on set as well for reference. The goal was to merge the two into a perfect replica.
“Denis really liked Loren’s performance when it was cut together, but part of our plan was to do a facial capture of Loren and Sean,” said Oscar-winning production visual effects supervisor John Nelson (“Gladiator”). “So on a secret Saturday [in Budapest] we brought in Sean and Loren using the DI4D PRO Facial Capture System, saying their lines.”
Oscar-winning MPC (“The Jungle Book”) was tasked with animating the 20-year-old Rachael. After getting the present-day scan of Young’s head, that reference was used to model an anatomically correct 3D skull. The digital sculpt provided a clear idea of the proportions of her head, including the bridge of the nose, cheekbones, and jaw line.
“We captured both actresses doing the scene in a controlled facial capture environment, but, in the end, because we wanted to tell this story with subtle changes, we ended up hand-animating the whole thing,” said MPC visual effects supervisor Richard Clegg.
