EXCLUSIVE: Sidney Flanigan wowed critics with her performance in Eliza Hittman’s Never Rarely Sometimes Always this year—the tale of a teenager forced to travel out of state for an abortion. And now, Deadline can confirm that she is set to star in Matthew Kaundart’s psychological drama My Twin Is Dead. This is Flanigan’s first role since Hittman’s film, for which Flanigan won the Best Actress award from the Boston Film Critics Association on Sunday.
