What actress played Liz Garrison in the movie "JFK"?

Sissy Spacek played Liz Garrison in the movie "JFK." Liz is the fictionalized film version of the wife of New Orleans district attorney Jim Garrison, played by Kevin Costner.

Released in 1991, "JFK" was directed and co-written by Oliver Stone. The film dramatizes Garrison's investigation into the assassination of President John F. Kennedy and blends historical figures with invented or heavily adapted scenes. Spacek's role is comparatively small but important because Liz represents the personal and family pressures surrounding Garrison's investigation.

The character is sometimes confused with real-life figures connected to the Kennedy assassination, including Lee Harvey Oswald's wife Marina or Jacqueline Kennedy. Spacek, an Oscar-winning actress known for films such as "Carrie" and "Coal Miner's Daughter," was not portraying one of those women. She was specifically cast as Liz Garrison, the wife of the central investigator.
