The official website for the "Attack on Titan" film adaptations just launched the first trailer as well as a couple of posters. The posters will begin appearing in Japanese theaters to promote the film starting April 25. The website also reveals that the first film is titled "Shingeki No Kyojin," which roughly translates to "Attack on Titan." The second film is titled "Attack on Titan: End of the World." 

As cited by Screen Rant, the trailer does not show off a lot of the main characters utilizing the anti-gravity 3D Maneuver Gear to quickly move around and fight the gigantic antagonists. It does, however, show off the film's special effects on the monsters and the explosive nature of the film's action sequences. 

Screen Rant notes that most of the film's action sequences were shot in the deserted location of Hashima Island. This is the same deserted island used for the "James Bond" film "Skyfall." With no human settlement around and no legal obstacles, the production team was allowed to conduct large-scale stunts and explosions. 

"Attack on Titan" centers around a band of humans fighting against giant humanoids known as Titans that devour human beings and destroy everything they come across in their path. 

Both films are based on the manga written and created by Hajime Isayama. The screenplay for both films was penned by Yusuke Watanabe, who previously worked on "Dragon Ball Z: Battle of Gods" and the live-action adaptation of "Gantz," another popular manga/anime series. Shinji Higuchi, director of "The Sinking of Japan," helms the films. 

"Attack on Titan" will be released in Japanese theaters on Aug. 1, while "Attack on Titan: End of the World" is scheduled for a Japanese release on Sept. 19. No official word has yet been given concerning a Western release, but given the worldwide popularity of the franchise, it is very likely that the films will see a limited Western theatrical run within the year.
