“The Dark Knight,” written by Christopher Nolan and Jonathan Nolan, remains one of the most quotable movies ever. Notable examples include Alfred Pennyworth (Michael Caine) telling Bruce Wayne (Christian Bale), “Some men just want to watch the world burn,” Joker’s sinister moments where he asks, “You wanna know how I got these scars?” and the Clown Prince of Crime’s “Why so serious?” So, while Christopher isn’t responsible for the iconic Harvey Dent line, he’s contributed dialogue that will stand the test of time.

For a while, Jonathan Nolan was mainly known for collaborating with his brother, co-writing “Memento,” “The Prestige,” “The Dark Knight,” “The Dark Knight Rises,” and “Interstellar.” However, he has emerged as a significant talent without the help of his maestro sibling. Jonathan is the creator, writer, director, and executive producer of the now-concluded science fiction dramas “Person of Interest” and “Westworld.” He’s also producing and directing multiple episodes of Amazon’s adaptation of the post-apocalyptic video game “Fallout,” a series he developed with his wife Lisa Joy. Looking further ahead, Jonathan, Joy, and Leonore Zion will be showrunners for the adaptation of the Norwegian crime novel “The Son.”

Jonathan remains booked and busy, establishing his own path apart from his brother. Still, he has bragging rights regarding the most iconic line in “The Dark Knight,” even if Christopher gets most of the credit for creating the beloved film.
