Adapting an existing work into a graphic novel is more than just providing pictures to words. Aside from editing for space and pacing, the adapter must choose an aesthetic that is true to the source's tone, and decide where and how to let the art do the talking. Here are 12 great adaptations of everything from novels to movies, video games, and even a government report. Each is a work of art in its own right, and while none of these will ever replace its original, they've certainly earned a spot alongside it on the shelf.

Archie Goodwin and Walt Simonson, two legendary comic creators take on Alien, Ridley Scott's science fiction/horror classic.

The Book of Genesis Illustrated by R. Crumb
W.W. Norton & Company, 2009

Legendary cartoonist Robert Crumb tries his hand at the Bible, visualizing all fifty chapters of the first book of the Old Testament.

Ponent Mon, 2009 (originally published 1986)

Written in 1906 by Natsume Soseki, Botchan is the story of the life of Botchan, a Toyko-native whose experience growing up outside of the Japanese capital reflected the culture's then shifting morality and complex relationship with Western ideas. It's considered a classic in Japan and is often read in schools. Beginning in the late 1980s, acclaimed mangaka Jiro Taniguchi began adapting much of the work in his emotive and sober style of storytelling.

Abrams, 2014

Their report, presented to President Lyndon Johnson in 1964, bolstered their original conclusion denying any conspiracy, despite conflicting narratives and dubious reporting. Now, 50 years later, writer Dan Mishkin, with artists Ernie Colon and Jerzy Drozd have used comics to offer a clear picture of the report and its purpose.

City of Glass
Picador, 2004 (originally published in 1994 by Avon Books)

The story centers on Daniel Quinn, a writer who inadvertently plays hard boiled detective on a case that leads him to discover many things about his employer, Peter Stillman, as well as a character named Paul Auster, and the author himself. Like the original prose novel, the adaptation has earned wide praise from both the comic book and literary world, particularly for Mazzucchelli's artistic imaginative renderings of Auster's words.

The Metamorphosis
Crown Publishing Group, 2003

After adapting various works by Franz Kafka in Give It Up! (NBM, 1995), illustrator Peter Kuper adapted the author's most enduring work, The Metamorphosis, the poignant story of Gregor Samsa, a man who is transformed into a giant bug. Using blocky, black and white forms, Kuper's interpretation captures much of the original's weird and comic tone, and is held in high regard by many literary scholars.

Prince of Cats
DC Comics/Vertigo, 2012

Artist Ronald Wimberly gives Shakespeare's Romeo and Juliet a modern, hip-hop influenced spin, with a retelling of the story from Tybalt's perspective.
