To create an atmosphere of horror, in addition to the director and screenwriter to tell a good story, undoubtedly actors are also a crucial part. The starring role of the film invited Sean Bing, who has a distinctive personality, who has always won the pursuit of a group of loyal fans with his unique style. Not long ago, the movie " Cash " (2010) in which he starred was intended to be released directly on DVD. It was precisely because of the appeal of Sean Bin’s fans that he was able to show his face in theaters, and its appeal is evident from this. This time, he appeared as a medieval knight, which is not difficult for him. In "In "(2001), he used to ride horses in armor, full of heroic spirit. However, this time he wants to hunt down the witch in a more gloomy atmosphere, and even more to show the heart of a knight who is struggling with the pain of faith in the era of plague-raging catastrophe. His acting skills are also a test. In comparison, Carice Anouk van Houten's glamorous witch looks more fascinating, and it will also become a key role in the film's turning point. Born in the Netherlands, Karlis often played various supporting roles in the film and television industry from the beginning of the film, until the stunning performance in "Black Book" (2006) made him famous in European film circles, and then continued the theme of World War II, with Tom Crew In " Valkyrie " (2008) further opened the door to Hollywood. This time working with a British director, from the World War II era to the medieval Black Death era, playing the role of a witch again, this is also an opportunity for her to break through in performance, and it is also worth looking forward to.
