Jason Jordan Segel (born January 18, 1980) is an American television and film actor, screenwriter, composer, puppeteer, musician, and singer, known for his work with producer Judd Apatow on the cult classic, short-lived television series Freaks and Geeks and Undeclared, the films Forgetting Sarah Marshall, Knocked Up, I Love You, Man, Gulliver's Travels, Bad Teacher, Despicable Me, and The Muppets, and also for his role as Marshall Eriksen in the CBS hit sitcom How I Met Your Mother.

Segel was born in Los Angeles, the son of Jillian (née Jordan), a homemaker, and Alvin G. Segel, a lawyer, and grew up in Pacific Palisades, California. His father is Jewish and his mother is Christian. He has stated that he was raised Jewish, as well as "a little bit of everything": he went to Hebrew school and had a Bar Mitzvah, and also attended St. Matthew's Parish School, a private Episcopal school. He has an older half-brother, Adam, and a younger sister, Alison. He has stated that he and Adam were not close while growing up.

The Greek is a fictional character on the HBO drama The Wire, played by actor Bill Raymond. The Greek is the head of an international criminal organization involved in narcotics and human trafficking. The Greek is a mysterious figure involved in numerous criminal activities. His given name is never mentioned on the show, and though he is known only as "The Greek", he has stated (in the episode Port in a Storm) that he is not actually Greek. A quiet and unassuming man, the Greek prefers to keep a low profile, operating all of his business through his lieutenant Spiros "Vondas" Vondopoulos. His smuggling organization operated from a small diner in Baltimore for years, and while Vondas would conduct business the Greek would listen in quietly at the counter. Nick Sobotka, upon seeing the Greek identify himself, was amazed that the shadowy figure had been in plain sight the entire time.

Despite his calm appearance, the Greek is cunning and ruthless, and only interested in facts that make him more money. Series creator David Simon has said that The Greek is an embodiment of raw unencumbered capitalism. Anyone interfering in this process is eliminated immediately, and he prefers to leave victims headless and handless to hinder identification.

Jason Reitman (born October 19, 1977) is a Canadian/Americanfilm director, screenwriter, and producer, best known for directing the films Thank You for Smoking (2005), Juno (2007), Up in the Air (2009), and Young Adult (2011).

His father is Jewish and was born in Czechoslovakia to Holocaust survivors, and his mother is Christian and of French-Canadian descent. When he was still a child, his family moved to Los Angeles. His father, Ivan, directed the successful films Ghostbusters, Stripes, and Kindergarten Cop. Jason described his childhood self as "a loser... a movie geek... [and] shy." In the late 1980s, Reitman began appearing in small acting parts and serving as a production assistant on his father's films. He spent time in the editing rooms of his father's movies, learning the process. Throughout his 20s, instead of accepting offers to make commercial feature films, Reitman began making his own short films and directing commercials. Although he was offered the opportunity to direct Dude, Where's My Car? on two separate occasions, he declined.
