Darren Lynn Bousman (born January 11, 1979) is an American film director and screenwriter.

Bousman was born in Overland Park, Kansas, the son of Nancy and Lynn Bousman. He is a graduate of the Film School at Full Sail University. He attended high school at Shawnee Mission North High School in Overland Park, and studied film at Full Sail University in Winter Park, Florida. Bousman got engaged to Laura Bosserman on October 4, 2008 and subsequently married her on January 2, 2010.

During 2004, he was pitching an idea for a movie called The Desperate to various American studios, who complained that the screenplay was too violent, and the plot was too close to Saw. David A. Armstrong who worked on Saw asked Bousman if he could show the script to Saw producer Gregg Hoffman. Hoffman read the script and called Bousman interested in producing "The Desperate", but after showing the script to his partners Mark Burg and Oren Koules, the two decided it would be the perfect opportunity to turn "The Desperate" into Saw II. Two months later, Bousman was flown to Toronto to direct.

Terrance Zdunich (/zˈduːnɪtʃ/) is an American actor, writer, composer, producer, illustrator and storyboard artist. He is most known for his role as Graverobber in the 2008 film Repo! The Genetic Opera.

After graduating from Otis College of Art & Design in 1998 Terrance took a job at Sony Animation drawing storyboards on such animated television shows as Roughnecks: The Starship Troopers Chronicles and Max Steel. Creatively frustrated, he left animation in 2002 to pursue freelance illustration gigs, including work on Fox’s television series Bones. As a storyboard artist he worked on live-action films such as What We Do Is Secret about the punk band The Germs, and Into The Wild, directed by Sean Penn. He also worked part-time teaching drawing and painting in Calabasas, California.

While transitioning from studio work in animation to life as a freelance artist, Terrance enrolled in an acting class at the South Coast Repertory Theatre where he met future collaborator Darren Smith. Together, in 1999 they formed "The Gallery" and the two began writing and performing theatrical rock music in the form of ten-minute operas. As a duo they played the Los Angeles club/theatre scene. Due to the positive response to their first ten-minute opera, The Necro-merchant's Debt, they decided to expand the piece into a full-length theatrical format which was later renamed Repo! The Genetic Opera.

Paris Whitney Hilton (born February 17, 1981) is an American businesswoman, potential future heiress, producer and socialite. She is a great-granddaughter of Conrad Hilton (founder of Hilton Hotels). Born in New York City and raised in both California and New York, Hilton began a modeling career as a teenager when she was with Donald Trump's modeling agency, T Management.

The show was a massive hit for the FOX network, premiering with 13 million viewers, and brought Hilton and co-star Richie to an international recognition. She then released her 2004 tongue-in-cheek autobiography called Confessions of an Heiress: A Tongue-in-Chic Peek Behind the Pose, she landed a supporting role in the 2005 horror film House of Wax, and recorded the 2006 music album Paris. She starred in the reality show Paris Hilton's My New BFF which was filmed in 2008 and also resulted in a second season. The show proved to be a success and was branched out to 2009's Paris Hilton's British Best Friend and Paris Hilton’s Dubai BFF. Hilton was in 2008's Repo! The Genetic Opera, where her work gained critical acclaim.

Costas Mandylor (born Costas Theodosopoulos; 3 September 1965) is a Greek Australian actor. He is perhaps best known for his role as Kenny in Picket Fences, and for portraying Mark Hoffman in the Saw films.

Mandylor was born in Melbourne, the son of Louise (née Mandylaris) and Yannis Theodosopoulos, who is a taxi driver. He is of Greek ancestry. Mandylor took his mother's maiden name citing his real name in Greek being too long. He grew up in St Kilda and South Melbourne. He moved to the United States in 1987 where he started taking acting lessons. He was initially unable to find any work acting and had to work any job available.

Mandylor's first major role was in the 1989 film Triumph of the Spirit playing a European Jew, which was filmed at the Auschwitz-Birkenau death camp. He returned to Los Angeles meeting director Oliver Stone and auditioned and got the role of an Italian count in The Doors (1991). Mandylor landed a leading role in Mobsters playing a New York gangster, Frank Costello. He went mentally prepared for the role, telling the Los Angeles Times, "It was interesting that I got that part, because I felt tuned in to gangsters, it was a genre I'd read a lot. When I was 13, I got a job as a dishwasher in a Melbourne nightclub and saw everything there, real gangsters, and had met characters who were dangerous people from an underground world." In 1992 he had a lead role on the CBS television drama, Picket Fences, playing officer Kenny Lacos until the show ended in 1996. Mandylor also had a lead role in the Saw films as Detective Mark Hoffman.
