25 Sep – Despite its title, the content delivered by "Joker" is no laughing matter as the movie tells the dark origin story of one of the biggest supervillains in the comic book universe. As its early October release in cinemas draws near, moviegoers, especially those in the United States where violence and mass shootings are prevalent, have been expressing their concern over the movie's possibility of influencing its audience to become violent. While some fans brush off the concern by saying that it's just a movie, the subject matter does prove to hit a little too close to home for certain people, especially for those who've experienced similar violence or knew someone who did. Case in point, the friends and families of a mass shooting that killed 12 and injured 70 during the screening of "The Dark Knight Rises" on 20 July 2012 in Aurora, Colorado.
