Samsung uploaded a new version of the Jackals trailer today--that is Samsung, as opposed to Samsung Peru, who upload the first trailer. Still only 30 seconds, but this one has a small amount of new footage. Keen-eyed Redditors note that Eva H.D. is credited as the film's writer, and she also seems to be playing the film's protagonist. Charlie is on board as director only.
You'll remember it was H.D.'s poem in I'm Thinking of Ending Things, and she also attended the same David Berman reading as Charlie at the beginning of this month.
