Who is Marta Kober?
Marta Kober is an American actress whose career peaked during the 1980s slasher film boom. Her most memorable role came in Friday the 13th Part 2 (1981), where she played Sandra, a camp counselor who becomes one of the film’s victims.
Beyond that breakout role, Marta built a steady career in both television and film throughout the 1980s. Her credits include guest appearances on popular series such as Happy Days, Magnum P.I., Matlock, and Full House, alongside roles in films like Neon Maniacs and Rad.
She also pursued a music career in the early 1990s. Performing under the name Marta Scorsese, she joined the punk rock group The Bomb.
Marta stepped away from acting in the mid-1990s and spent many years out of the public eye. She returned briefly in 2021 with an appearance in Coroner’s Report, and in August 2026, she appeared at the MonsterMania horror convention in Cherry Hill, New Jersey, alongside her Friday the 13th Part 2 co-star Bill Randolph.

She spent her childhood and teenage years in the city, surrounded by its fast-paced energy and access to the entertainment industry.
Her parents kept a low profile, and she has not publicly shared details about her family background.
However, her enrollment at one of New York’s most competitive performing arts schools signals that she showed strong artistic talent from a young age.
Growing up in New York City gave Marta direct access to the television and film industry. She began appearing on television while still in her early teens, before she had even completed high school.
Marta Kober Age
Marta Kober is 62 years old as of 2026, born on October 23, 1963. Her birthday falls under the Scorpio zodiac sign.
Her debut in Friday the 13th Part 2 came when she was just 17 years old at the time of filming.
Marta Kober Ethnicity and Nationality
Marta Kober holds American nationality, born and raised in New York City. Her ethnicity is Caucasian, as confirmed across multiple biographical sources covering her career.
She grew up as a native New Yorker, shaped by the cultural diversity and creative energy of the city. That upbringing gave her early access to the performing arts world that defined her career.
Marta Kober Height and Weight
Marta Kober stands at approximately 5 feet 3 inches tall, which is equivalent to about 1.60 meters. Her weight has been reported at approximately 120 lbs, or around 55 kg.
She has light brown hair and brown eyes. Throughout her career in the 1980s, her girl-next-door appearance made her a natural fit for the teen roles common in that era’s horror and drama productions.
Marta Kober Education
Marta Kober attended Fiorello H. LaGuardia High School of Music and Art and Performing Arts in New York City. The school, located on the Upper West Side of Manhattan, is one of the most selective public performing arts schools in the United States.
Her classmates at LaGuardia included actors Wesley Snipes and Esai Morales, among other future entertainment figures.
The school’s rigorous conservatory-style training gave her a strong foundation in the craft before she began her professional career.
Marta Kober Career
Marta Kober’s professional screen career began in the late 1970s and extended into the 1990s, covering a wide range of television and film roles.
Her work during this period reflects the breadth of 1980s American genre entertainment.
Early Television Work and Friday the 13th Part 2
Marta made her screen debut in 1978 on NBC Special Treat, playing Stacy in the episode “Rodeo Red and the Runaway.” That early television credit gave her practical on-set experience before she had finished high school.
In 1981, she landed the role that would define her legacy: Sandra in Friday the 13th Part 2, directed by Steve Miner. The film starred Amy Steel, John Furey, and Adrienne King, and continued the slasher franchise that the original 1980 film had launched.
Marta’s character Sandra sneaks off with her boyfriend Jeff to explore the forbidden grounds near Camp Crystal Lake. The couple’s fate at the hands of Jason Voorhees became one of the film’s most remembered sequences.
A notable piece of production history surrounds her involvement. Marta was 16 years old at the time of filming and had misrepresented her age to get the role.
When producers discovered her actual age, her nudity was edited out of the final cut of the film. She turned 17 shortly before the film’s release, and the role placed her firmly among the scream queens of that era.
Television Guest Roles and Genre Films
After Friday the 13th Part 2, Marta continued working in both television and film throughout the 1980s. In 1982, she appeared in a segment of ABC’s Afterschool Specials. In 1983, she played Amanda in Enormous Changes at the Last Minute and Debra in Baby, It’s You.
The year 1984 brought several significant credits. She appeared in the TV movie A Touch of Scandal, playing Toni Allenby. That same year, she also appeared in Shattered Vows, Second Sight: A Love Story, and a guest role as Jesse Broderick on Happy Days.
In 1985, her credits included the TV movie Heart of a Champion: The Ray Mancini Story, where she played Sandy, as well as Children of the Night (TV movie) and the comedy film School Spirit, where she played Ursula Grimshaw.
The year 1986 was particularly active. She appeared in the horror film Neon Maniacs, playing Lorraine, and in the BMX sports film Rad, where she played Becky.
Both films found their audiences on home video and late-night cable throughout the 1980s. That same year she also guest-starred as Mary Elizabeth in a 1986 episode of Magnum, P.I.
In 1987 she appeared in Matlock in a guest role and in the TV movie Downpayment on Murder. Her final major theatrical credit in this period was Slumber Party Massacre III in 1990, followed by Inside Out in 1991.
Later Work and Return to the Public Eye
After a guest appearance on Full House in 1992 and a 1995 appearance on Law and Order, Marta largely stepped away from acting. For much of the late 1990s and 2000s, she remained out of the public eye.
In 1993, she pursued music under the name Marta Scorsese with the punk rock group The Bomb, alongside Jeff Pezzati, Steve Albini, Mike Soucy, and Paul Garcia.
In 2021, she made a return to screens with a role in Coroner’s Report, a genre series revisiting iconic horror film characters. Marta reprised her role as Sandra from Friday the 13th Part 2 in the project.
By August 2026, she had returned to horror convention appearances. She appeared at the MonsterMania convention in Cherry Hill, New Jersey, on the weekend of August 2026, alongside co-star Bill Randolph, who had played her boyfriend Jeff in Friday the 13th Part 2.
This marked her first major convention appearance and gave longtime fans their first chance to meet her in person.
