Bong Joon Ho’s follow-up film to his Oscar-winning “Parasite” is gaining quite the ensemble, as sources tell Deadline that Toni Collette and Mark Ruffalo (whose deals are in final negotiations), along with Naomi Ackie, are joining Robert Pattinson in Bong’s next feature at Warner Bros. The untitled film is based on the novel Mickey7 by Edward Ashton. The book was published in February by St. Martin, a Macmillan imprint. While the film will be inspired by the novel, sources say that given Bong’s past experiences with adaptations, his version might ultimately may be different from the novel’s. The novel’s story follows Mickey7, who is an Expendable: a disposable employee on a human expedition sent to colonize the ice world Niflheim. Whenever there’s a mission that’s too dangerous—even suicidal—the crew turns to Mickey. After one iteration dies, a new body is regenerated with most of his memories intact. After six deaths, Mickey7 understands the terms of his deal…and why it was the only colonial position unfilled when he took it. The Warner Bros. Pictures feature marks Bong’s second project with Warner Bros.
