Ang Lee mentions Kristen at 58.14mins (translation):
- He sent the script and she accepted the part. It's their 1st phone call.
- Ang Lee remembered Kristen from Into the Wild. Impressive performance. Kristen rehearsed with Joe without make up.
If you don't understand Mandarin, it's interesting to hear Joe Alwyn's answers throughout the press conference too (in English).
Thanks to @CiderFlood for the video and translation of Ang Lee's comments on Kristen.
