Zhang Yimou Is Still Reworking the Script for His Three-Body Problem Film

Years into the process, Zhang Yimou says he is still reworking the screenplay for his film adaptation of "The Three-Body Problem." He gave the update at the opening ceremony of the Busan International Film Festival, where he is president of this year's competition jury, in conversation with festival director Jung Hanseok.

A marquee director's adaptation sitting at the script-polishing stage years after it was set in motion is a useful corrective to how big projects are announced — as commitments rather than drafts.
