Question: Stephen King's serial novel about an unusual inmate who displays healing and empathetic abilities was adapted into a film by what director?
Context: The Green Mile is a 1999 American fantasy crime drama film written and directed by Frank Darabont and adapted from the 1996 Stephen King novel of the same name. A healing factor is the ability of some characters in fiction to recover from bodily injuries or disease at a superhuman rate.  Since the introduction of Wolverine by Marvel Comics in 1974 and inspired by the immense popularity of the character, superhuman healing has become a fairly common power featured in comic books, novels, television, film, and other media.  The overall efficiency of a character's healing factor often fluctuates due to various writers applying a very broad degree of artistic license.  Weapon X has been established, on multiple accounts for having the fastest healing factor over all mutants, with the exception of external factors.  As a result, especially concerning characters depicted in comic books, it has become a very common source of debate among fans.  Over the years, it has also become common for healing factors to have an umbrella effect, serving as a partial source for multiple superhuman abilities; various powers thus demonstrated include superhuman strength, speed, stamina, agility, reflexes, durability and/or senses, to name the most common.  The source of a character's healing factor, depending upon the medium, usually ranges from natural genetic mutation, accidental exposure to radioactive materials, artificially-induced genetic enhancement, cybernetic augmentation, magic or even a combination of different factors.  Despite the ability to quickly recover from wounds, characters with a healing factor are still capable of feeling pain. The Green Mile is a 1996 serial novel written by Stephen King.

The manuscript is about magic, but it also contains photographs that seem very real.

Indigo children, according to a pseudoscientific New Age concept, are children who are believed to possess special, unusual, and sometimes supernatural traits or abilities.  They are sometimes also referred to as crystal children or star children.  The idea is based on concepts developed in the 1970s by Nancy Ann Tappe and further developed by Jan Tober and Lee Carroll.  The concept of indigo children gained popular interest with the publication of a series of books in the late 1990s and the release of several films in the following decade.  A variety of books, conferences and related materials have been created surrounding belief in the idea of indigo children and their nature and abilities.  The interpretations of these beliefs range from their being the next stage in human evolution, in some cases possessing paranormal abilities such as telepathy, to the belief that they are more empathetic and creative than their peers.
