Max von Sydow
The late Max von Sydow, who famously appeared as The Three-Eyed Raven in Game of Thrones and the star of various iconic Ingmar Bergman movies, played the small role of Lor San Tekka in The Force Awakens.
An explorer and member of the Church of the Force, San Tekka became a believer in the ideals of the Jedi Order during the Clone Wars, despite not being Force-sensitive. At the beginning of the movie, he gave Poe Dameron (Oscar Isaac) the map fragment that would lead the Rebels to Luke Skywalker (Mark Hamill). Soon after that, San Tekka was captured by Kylo Ren, who demanded to know where the map was. When San Tekka refused to comply, Ren killed him.
