Marty Belafsky (born September 19, 1975) is an American actor/comedian born in Los Angeles, California.
 He began acting professionally at age 13 and was soon cast as Louis Plumb on the short-lived NBC series "Hull High".
 Shortly thereafter, Belafsky landed the role of Crutchy in the Disney musical film, "Newsies".
 He continued acting through his teens, making appearances in such television shows as "The Wonder Years", "Great Scott" and "Step By Step" and the film "Wrestling Ernest Hemingway".
 Belafsky also voiced Kent Swanson in the video game series "Dead Rising" released in 2006.
Richard Zampella is an American film and multimedia producer, who has collaborated with John Mulholland (director) on three documentaries films including; Sergeant York of God & Country (Warner Home Video—Narrated by Liam Neeson), Inside High Noon (Lions Gate Entertainment—Narrated by Frank Langella) and Cooper & Hemingway: The True Gen (Narrated by Sam Waterston).
 Cooper & Hemingway: The True Gen was reviewed by The New York Times film critic Andy Webster on October 11, 2013 and was named an NY Times Critics’ Pic by Manohla Dargis, A. O. Scott and Stephen Holden.
 Webster said the picture was proof that the work of these two men "endures and so does what they stood for".
True at First Light is a book by American novelist Ernest Hemingway about his 1953–54 East African safari with his fourth wife Mary, released posthumously in his centennial year in 1999.
 The book received mostly negative or lukewarm reviews from the popular press and sparked a literary controversy regarding how, and whether, an author's work should be reworked and published after his death.
 Unlike critics in the popular press, Hemingway scholars generally consider "True at First Light" to be complex and a worthy addition to his canon of later fiction.
Witches of East End is a 2011 novel by author Melissa de la Cruz and the first entry in her "Beauchamp Family" series.

 "Witches of East End" is de la Cruz's first adult novel; she said she wrote it with her Blue Bloods audience in mind because "many of them will soon be adults" and the book takes place in the same universe as the "Blue Bloods" series.
 The novel currently has two sequels: "Serpent's Kiss" (2012) and "Winds of Salem" (2013).

Running from Crazy is a 2013 television documentary film by director Barbara Kopple about the family of Mariel Hemingway, grand daughter of Nobel Prize-winning author Ernest Hemingway.
 Through the eyes of Mariel, who received an Oscar nomination for her role in Woody Allen's 1979 film "Manhattan", and who has spoken for the American Foundation for Suicide Prevention, it chronicles the story of three of the author's grandchildren; Mariel, Margaux Hemingway and Joan "Muffet" Hemingway, daughters of Jack Hemingway, and their struggles with the family history of substance abuse, mental illness and suicide.
 First shown at the 2013 Sundance Film Festival, the documentary was promoted on the Oprah Winfrey Network, which aired its premiere on April 27, 2014.
