Context: Michael Gandolfi (born January 31, 1962) is an American actor, producer, and writer.  He is best known for playing Andrew on the WB drama series, "Gilmore Girls", and as a writer on the sitcom Roseanne." John Stephen Goodman (born June 20, 1952) is an American actor.  Early in his career, he was best known for playing Dan Conner on the ABC TV series "Roseanne" (1988–1997), for which he won a Golden Globe Award for Best Actor in 1993.  He is also a regular collaborator with the Coen brothers on such films as "Raising Arizona" (1987), "Barton Fink" (1991), "The Big Lebowski" (1998), "O Brother, Where Art Thou? " (2000), and "Inside Llewyn Davis" (2013).  Goodman's voice roles in animated films include Pacha in Disney's "The Emperor's New Groove" (2000), and Sulley in Pixar's "Monsters, Inc." (2001), and "Monsters University" (2013). A character (sometimes known as a fictional character) is a person or other being in a narrative work of art (such as a novel, play, television series, or film).  The character may be entirely fictional or based on a real-life person, in which case the distinction of a "fictional" versus "real" character may be made.  Derived from the ancient Greek word χαρακτήρ, the English word dates from the Restoration, although it became widely used after its appearance in "Tom Jones" in 1749.  From this, the sense of "a part played by an actor" developed.  Character, particularly when enacted by an actor in the theatre or cinema, involves "the illusion of being a human person."  In literature, characters guide readers through their stories, helping them to understand plots and ponder themes.  Since the end of the 18th century, the phrase "in character" has been used to describe an effective impersonation by an actor.  Since the 19th century, the art of creating characters, as practiced by actors or writers, has been called characterisation. Dan Conner is a primary fictional character in the "Roseanne" television series.  He is the husband to fellow primary character Roseanne Conner, and father to two daughters Darlene and Becky Conner, and two sons D.J. Conner and Jerry Garcia Conner.  He is portrayed by John Goodman. Michael Aaron Fishman (born October 22, 1981 in Los Angeles, California) is an American actor, writer and producer best known for playing D.J.

He was played originally by Sir Nigel Hawthorne, both on stage and in a television adaptation of the stage show by Henry Goodman in a new series of "Yes, Prime Minister".  In "Yes Minister", he is the Permanent Secretary for the Department of Administrative Affairs (a fictional department of the British government).  In the last episode of "Yes Minister", "Party Games", he becomes Cabinet Secretary, the most powerful position in the service and one he retains during "Yes, Prime Minister".

Dr. James Kildare is a fictional American medical doctor character, originally created in the 1930s by the author Frederick Schiller Faust under the pen name Max Brand.  Shortly after the character's first appearance in a magazine story, Paramount Pictures used the story and character as the basis for the 1937 film "Internes Can't Take Money".  Metro-Goldwyn-Mayer (MGM) subsequently acquired the rights and featured Kildare as the primary character in a series of American theatrical films in the late 1930s and early 1940s, several of which were co-written by Faust (as Max Brand), who also continued to write magazine stories and novels about the character until the early 1940s.  The Kildare character was later featured in an early 1950s radio series, a 1960s television series, a comic book and comic strip based on the 1960s TV show, and a short-lived second 1970s television series. Dr. Jack Shephard is a fictional character and the main protagonist of the ABC television series "Lost", played by Matthew Fox.  "Lost" follows the journey of the survivors of Oceanic Airlines flight 815 on a mysterious island and their attempts to survive and escape, slowly uncovering more of the much broader island history they are a part of.  The character was originally conceived by creator J. J. Abrams, though the direction of storylines owes more to co-creator Damon Lindelof and fellow showrunner Carlton Cuse.  J.J. Abrams, the creator of "Lost", once told "Entertainment Weekly", "Jack Shephard may be the greatest leader in any television series."  Actor Matthew Fox would have some influence on the character during the course of the series' production.  For example, Fox's own tattoos were incorporated into the character's backstory.  Although at an early stage in the show's development, the character was originally intended to die in the pilot, the writers soon changed this plan, and Jack became the show's main character from its pilot episode onwards.
