Louis Leterrier, the director of the original “Incredible Hulk” film, engaged in a conversation with ComicBook.com, delving into the multifaceted nature of the Hulk character. He highlighted the complexity of the character’s various personas, including Smart Hulk. Leterrier noted that while the primeval and rage-filled Hulk possesses a raw intensity, the introduction of Grey Hulk and Smart Hulk versions slightly shifts the tone toward a more lighthearted and childlike disposition.
