Released in 1994, Oliver Stone's 'Natural Born Killers' follows lovers Mickey and Mallory Knox (Woody Harrelson and Juliette Lewis) as they go on a mass-murdering spree, which eventually becomes glorified by the media and a fame-hungry reporter (Robert Downey Jr.). Though it wasn't a hit at the box office, the divisive crime film, which was based on a story by Quentin Tarantino, went on to gain a following and has become regarded by many as a classic. 'Natural Born Killers' celebrates its 20th anniversary this year, so join us as we look back at the cast of the film and see what they're up to now.

Then: Woody Harrelson, then best known for his role on the long-running sitcom 'Cheers,' played Mickey Knox, who teams up with and marries Mallory Wilson; the pair go on a mass-murdering spree filled with outlandish violence.

Now: Harrelson is known for his work in films like 'The People vs. Larry Flynt,' 'EDtv,' 'No Country for Old Men,' and 'Zombieland.' In 2013 alone, he appeared in four films: 'Now You See Me,' 'Out of the Furnace,' lending his voice to the animated kids' film 'Free Birds,' and reprising the role of Haymitch Abernathy in 'The Hunger Games: Catching Fire.' Harrelson currently stars on the new HBO series 'True Detective' with his best friend and fellow actor Matthew McConaughey.

Then: Juliette Lewis played Mallory, a young woman from an abusive home who is rescued by Mickey. The two damaged souls marry each other and go on a violent crime spree. Oliver Stone approached musician Tori Amos for the role, but insisted on using her song "Me and a Gun," which detailed the singer's real-life personal account of her own rape, during every scene in which Mallory kills someone. Amos slapped Stone and refused to take the part. Instead, the role went to Lewis, who had previously appeared in gritty crime films like 'Cape Fear' and 'Kalifornia.'

Now: Lewis went on to appear in 'From Dusk Till Dawn,' which was written by and co-starred Quentin Tarantino. In recent years she's appeared in the films ‘The Switch,’ ‘Due Date,’ and ‘Hick,’ and can be seen alongside Meryl Streep in ‘August: Osage County,' which has been garnering some awards buzz. In addition to acting, Lewis is also a musician and was the frontwoman of the rock band Juliette and the Licks until 2009, when she went solo.

Robert Downey Jr., Wayne Gale

Then: Robert Downey Jr. played Wayne Gale -- once a prominent and serious Australian journalist, Gale is now the host of American Maniacs, a sensational tabloid news program. The character of Gale was based on real-life Australian reporter Steve Dunleavy, with whom Downey Jr. met to research the role.

Now: Downey Jr. fell on some hard times in the mid to late 90s, but revived his career with parts in films like 'Good Night, and Good Luck,' 'Kiss Kiss Bang Bang' and 'Zodiac.' In 2010, he reunited with Juliette Lewis for the comedy film 'Due Date.' Today he's best known for portraying Tony Stark in Marvel's 'Iron Man' and 'Avengers' films, and he can be seen next in 'Chef,' directed by his 'Iron Man' and 'Iron Man 2' director and co-star Jon Favreau.

Now: Sizemore has appeared in films like 'Heat,' 'Saving Private Ryan,' 'Bringing Out the Dead,' and 'Black Hawk Down.' In 2003, he was arrested on charges of assault and battery, and his subsequent and highly-publicized struggles with substance abuse led him to a stint on 'Celebrity Rehab with Dr. Drew.' He's been trying to turn his career around ever since, appearing mostly in B-movies. Recently, he starred in the films 'Company of Heroes,' 'Reach Me,' and 'Paranormal Movie,' and had a recurring role on 'Hawaii Five-0.'

He appeared in both 'Casper' live-action films, was the star and writer of 'Meet Wally Sparks,' and played the devil in the Adam Sandler comedy 'Little Nicky.'
