Question: What type of media are both Shutter Island and Invasion of the Body Snatchers?
Context: Body Snatchers is a 1993 American science fiction horror film directed by Abel Ferrara and starring Gabrielle Anwar, Billy Wirth, Terry Kinney, Meg Tilly, Christine Elise, R. Lee Ermey and Forest Whitaker.  It is loosely based on the 1955 novel "The Body Snatchers" by Jack Finney. Invasion of the Bunny Snatchers is a Bugs Bunny short subject directed by Greg Ford and Terry Lennon and released in 1992.  The cartoon was intended for theatrical release but eventually aired as part of the television special "Bugs Bunny's Creature Features".  Its premise is modeled after "Invasion of the Body Snatchers", and it is considered subversive, critical of the greed of its production studio Warner Bros., and a lampoon of cheaply-drawn animation. Shutter Island is a 2010 American neo-noir psychological thriller film directed by Martin Scorsese and written by Laeta Kalogridis, based on Dennis Lehane's 2003 novel of the same name.  Leonardo DiCaprio stars as U.S. Marshal Edward "Teddy" Daniels who is investigating a psychiatric facility on Shutter Island after one of the patients goes missing.  Mark Ruffalo plays his partner officer, Ben Kingsley is the facility's lead psychiatrist, and Michelle Williams is Daniels' wife.  The film received generally favorable reviews from critics and grossed over $294 million at the box office. Shutter Island is a best-selling novel by Dennis Lehane, published by Harper Collins in April 2003.  A film adaptation was released in February 2010.  Lehane has said he sought to write a novel that would be a homage to Gothic settings, B movies, and pulp.  He described the novel as a hybrid of the works of the Brontë sisters and the 1956 film "Invasion of the Body Snatchers".  His intent was to write the main characters in a position where they would lack 20th century resources such as radio communications.  He also structured the book to be more taut than his previous book, "Mystic River". Jack Finney (October 2, 1911 – November 14, 1995) was an American author.  His best-known works are science fiction and thrillers, including "The Body Snatchers" and "Time and Again".  The former was the basis for the 1956 movie "Invasion of the Body Snatchers" and its remakes. Pod people (also known as The Body Snatchers) is a nickname given to an alien species featured in the 1955 novel "The Body Snatchers" by Jack Finney, the 1956 film "Invasion of the Body Snatchers", the 1978 remake of the same name and the 1993 film "Body Snatchers".  Not to be confused with the 2007 film "Invasion of the Pod People" though they share similar themes. Invasion of the Body Snatchers is a 1978 American science fiction horror film directed by Philip Kaufman, and starring Donald Sutherland, Brooke Adams, Veronica Cartwright, Jeff Goldblum and Leonard Nimoy.  Released on December 22, 1978, it is a remake of "Invasion of the Body Snatchers" (1956), which is based on the novel "The Body Snatchers" by Jack Finney.  The plot involves a San Francisco health inspector and his colleague who discover that humans are being replaced by alien duplicates; each is a perfect copy of the person replaced, only devoid of human emotion. Invasion is an American science fiction television series that aired on ABC for one season beginning in September 21, 2005.  Somewhat similar to "Invasion of the Body Snatchers", the show told the story of the aftermath of a hurricane in which water-based creatures infiltrate a small Florida town and begin to take over the bodies of the town's inhabitants through a cloning process (first by merging with and then unknowingly replacing them).  The show was produced by Shaun Cassidy Productions and Warner Bros.  Television. Invasion of the Body Snatchers is a 1956 American science fiction horror film produced by Walter Wanger, directed by Don Siegel, that stars Kevin McCarthy and Dana Wynter.  The black and white film, shot in Superscope, was partially done in a film noir style.  Daniel Mainwaring adapted the screenplay from Jack Finney's 1954 science fiction novel "The Body Snatchers".  The film was released by Allied Artists Pictures on a double bill with the British science fiction film "The Atomic Man". The graphic novel adaptation of Shutter Island by Christian De Metter, published by TOKYOPOP and William Morrow, is based on Dennis Lehane's bestseller novel "Shutter Island".
