Jalmari Helander, the director of the Finnish action extravaganza Sisu, is back for a second round of violent vengeance this fall with Sisu: Road to Revenge. After that, however, he’s tackling one of the most iconic franchises in action history: Rambo. Collider’s Perri Nemiroff sat down with Helander at Fantastic Fest in Austin, Texas, where Sisu: Road to Revenge had its world premiere, and talked about his approach to the venerable shoot-em-up series.
