John Guilbert Avildsen (born December 21, 1935) is an American film director.

Avildsen was born in Oak Park, Illinois, the son of Ivy (née Guilbert) and Clarence John Avildsen. After starting out as an assistant director on films by Arthur Penn and Otto Preminger, John Avildsen received his first success with the low budget feature Joe (1970) which received critical acclaim for star Peter Boyle and moderate box office business.

This was followed by another critical success, Save the Tiger (1973), that was nominated for three Oscars, winning Best Actor for star Jack Lemmon.

Avildsen's greatest success was Rocky (1976), garnering ten Academy Award nominations and winning three, including Best Picture and Best Director. He later directed what was expected to be the series' final installment, Rocky V (1990). His other films include Cry Uncle! (1970), Neighbors (1981), The Karate Kid (1984) The Karate Kid, Part II (1986), The Karate Kid, Part III (1989), Lean on Me (1989), and 8 Seconds (1994).

Oliver Burgess Meredith (November 16, 1907 – September 9, 1997), known professionally as Burgess Meredith, was an American actor in theatre, film, and television, who also worked as a director. Active for more than six decades, Meredith has been called "a virtuosic actor" who was "one of the most accomplished actors of the century." Meredith won several Emmys, was the first man to win two times the Saturn Award for Best Supporting Actor, and was nominated for Academy Awards.

Meredith was born in Cleveland, Ohio, the son of Ida Beth (née Burgess) and Canadian-born William George Meredith, M.D.

He graduated from Hoosac School in 1926 and then attended Amherst College as a member of the Class of 1931. Meredith served in the United States Army Air Forces in World War II, reaching the rank of captain. He was discharged in 1944 to work on the movie The Story of G.I. Joe, in which he starred as the popular war correspondent Ernie Pyle.

In 1933, he became a member of Eva Le Gallienne's Civic Repertory Theatre company in New York City. Although best known to the larger world audience for his film and television work, Meredith was an influential actor and director for the stage. He made his Broadway debut as Peter in Le Gallienne's production of Romeo and Juliet (1930) and became a star in Maxwell Anderson's Winterset (1935), which became his film debut the following year. His early life and theatre work were the subject of a New Yorker profile.

Michael Sylvester Gardenzio Stallone (/stəˈloʊn/; born July 6, 1946), commonly known as Sylvester Stallone, and nicknamed Sly Stallone, is an American actor, filmmaker, screenwriter, film director and occasional painter. Stallone is known for his machismo and Hollywood action roles. Two of the notable characters he has portrayed are boxer Rocky Balboa and soldier John Rambo. The Rocky and Rambo franchises, along with several other films, strengthened his reputation as an actor and his box office earnings.

Stallone's film Rocky was inducted into the National Film Registry as well as having its film props placed in the Smithsonian Museum. Stallone's use of the front entrance to the Philadelphia Museum of Art in the Rocky series led the area to be nicknamed the Rocky Steps. Philadelphia has a statue of his Rocky character placed permanently near the museum, on the right side before the steps. It was announced on December 7, 2010 that Stallone was voted into boxing's Hall of Fame.

Sylvester Stallone was born Michael Sylvester Gardenzio Stallone in New York City, the elder son of Frank Stallone, Sr., a hairdresser, and Jackie Stallone (born Jacqueline Labofish), an astrologer, former dancer, and promoter of women's wrestling. His younger brother is actor and musician Frank Stallone. Stallone's father was born in Gioia del Colle, Apulia, Italy, and emigrated to the United States as a child. Stallone's mother is of half Russian Jewish and half French descent.

Robert "Rocky" Balboa, Sr. is a fictional character and the protagonist of the Rocky series from 1976 to 2006. During the series, he wins the Heavyweight Championship of the World twice. He was portrayed by Sylvester Stallone.

Robert Balboa was born on April 6, 1946. He was the only child to a Roman Catholic Italian-American family. It was revealed in Rocky II that Rocky's black trunks with gold trim were the colors of his high school that he never graduated from. During the scene in which Rocky takes Adrianna "Adrian" Pennino skating on Thanksgiving, he tells her "Yeah -- My ol' man who was never the sharpest told me -- I weren't born with much brain so I better use my body." This encouraged him to take up boxing. He trained very hard so he could grow up to be like his idol Rocky Marciano. Unable to live on the small pay of club fights, and being unable to find work anywhere else, Rocky got a job as a collector for Tony Gazzo, the local loan shark, just to make ends meet. By late 1975, Rocky had fought in 64 fights, winning 44 (38 KO'S) and losing 20. Rocky was proud that he never had his nose broken in a professional fight. His nickname is "The Italian Stallion," spawning from his Italian-American heritage.
