Lee Harvey Oswald in the context of "Assassination of John F. Kennedy"

Sir Gary Leonard Oldman (born 21 March 1958) is an English actor and filmmaker. Known for his versatility and intense acting style, he has received various accolades, including an Academy Award, a Golden Globe Award, three British Academy Film Awards and nominations for three Primetime Emmy Awards. His films have grossed over US$11 billion worldwide, making him one of the highest-grossing actors of all time.

Oldman began acting in theatre in 1979 and made his film debut in Remembrance (1982). He appeared in the Royal Court Theatre in London and was a member of the Royal Shakespeare Company, with credits including Cabaret, Romeo and Juliet, Entertaining Mr Sloane, Saved, The Country Wife and Hamlet. He rose to prominence in British film with his portrayals of Sid Vicious in Sid and Nancy (1986), Joe Orton in Prick Up Your Ears (1987) and Rosencrantz in Rosencrantz & Guildenstern Are Dead (1990). Regarded as a member of the "Brit Pack", he achieved greater recognition as an American gangster in State of Grace (1990), Lee Harvey Oswald in JFK (1991) and Count Dracula in Bram Stoker's Dracula (1992).

Henry Menasco Wade (November 11, 1914 – March 1, 2001) was an American lawyer who served as district attorney of Dallas County from 1951 to 1987. He participated in two notable U.S. court cases of the 20th century: the prosecution of Jack Ruby for killing Lee Harvey Oswald, and the U.S. Supreme Court case that held abortion was a constitutional right, Roe v. Wade. In addition, Wade was district attorney when Randall Dale Adams, the subject of the 1988 documentary film The Thin Blue Line, was wrongfully convicted in the murder of Robert Wood, a Dallas police officer. After his term and death, he was criticised for his corruption, ranging from wrongful convictions, to attitudes and certain comments on race, in addition to some decisions such as execution of innocent men.

The Texas School Book Depository, later known as the Dallas County Administration Building and now "The Sixth Floor Museum", is a seven-floor building facing Dealey Plaza in Dallas, Texas. Lee Harvey Oswald was working as an employee at the building when he assassinated United States President John F. Kennedy on November 22, 1963. Official government investigations concluded that Oswald shot Kennedy from a sixth floor window on the building's southeastern corner. The building, located at 411 Elm Street on the northwest corner of Elm and North Houston Streets in downtown Dallas, is a Texas Historic Landmark.

J. D. Tippit (September 18, 1924 – November 22, 1963) was an American World War II U.S. Army veteran and Bronze Star recipient, who was a police officer with the Dallas Police Department from 1952 to 1963. On November 22, 1963, less than an hour after the assassination of president John F. Kennedy, Tippit was shot and killed in a residential neighborhood in the Oak Cliff section of Dallas, Texas. Lee Harvey Oswald was initially arrested for the murder of Tippit and was subsequently charged with killing Kennedy, but he was murdered by Jack Ruby, a Dallas nightclub owner, two days later, before he could be tried. In 1964, the Warren Commission concluded that Tippit was killed by Oswald acting alone, though Tippit's murder has spawned alternative scenarios from Kennedy assassination conspiracy theorists.

Jack Leon Ruby (born Jacob Leon Rubenstein; c. March 25, 1911 – January 3, 1967) was an American nightclub owner who murdered Lee Harvey Oswald on November 24, 1963, two days after Oswald was arrested for the assassination of President John F. Kennedy.

Born in Chicago, Ruby operated nightclubs in Texas. On November 24, 1963, two days after Kennedy was assassinated in Dallas, Ruby shot and mortally wounded Oswald in Dallas Police Headquarters and was immediately arrested. The shooting happened on live television. Ruby was convicted and sentenced to death. This was overturned on appeal, and he was granted a new trial, but Ruby fell ill, was diagnosed with cancer, and died of a pulmonary embolism on January 3, 1967.
