 In 2005 , Constantine was released , a feature film that did not use the same title as the comic book , in order to avoid confusion with the <unk> horror franchise . The only links to the character of John Constantine were the name and a plotline loosely based on the " Dangerous Habits " story arc ( Hellblazer # 41 – 46 ) . DC Comics announced a sequel to the 2005 Constantine movie was in the works , with producer Lorenzo di Bonaventura linked to the project . He stated : " I 'd love to do it ... We want to do a hard , R @-@ rated version of it . We 're going to scale back the size of the movie to try and persuade the studio to go ahead and make a tough version of it . " In late 2012 , director Guillermo del Toro publicly discussed the notion of creating a film that would star John Constantine alongside other DC / Vertigo characters such as Zatanna , Swamp Thing , and more .
