Sounding like a blend of numerous classic sci-fi tales from “Day of the Triffids” to “Invasion of the Body Snatchers,” this new feature deals with a genetically engineered plant scattering its seeds and causing uncanny changes to living creatures around the glove. The afflicted appear strange as if they were replaced by copies that aren’t quite right. Jessica Hausner, who delivered the superb “Lourdes” and “Amour Fou,” helms this project which stars Ben Whishaw, Emily Beecham and Kerry Fox. It’s expected to be done by the Spring and could see a Fall festival rollout.
