Helen Slater

In 2010, Slater wrote a Supergirl story titled "A Hero's Journey" which appeared in the fiftieth issue of the fifth volume of the Supergirl comic book.

In 2003, she released a CD, One of These Days, consisting of her original songs. The tracks were real-time recordings with Slater singing and playing piano, accompanied by six other musicians; no multitracking, editing, or dubbing was employed. In 2005, she released a second CD, Crossword, which used the same recording approach as the first CD. Both albums were produced by Phil Swann. In 2008, Cortes Alexander recorded Slater's "Any Day Now" and "Love'll Come & Do Just That" on his album Swell. Her third album, Shine, was released in 2010.

In the 2000s, Slater recorded five albums, singing her own compositions and playing the piano.

Slater has appeared on episodes of various television series, including The New Adventures of Old Christine, Supernatural, four episodes as the voice of Talia in Batman: The Animated Series, and others. She was a series regular on the half-season run of the 1990 ABC newsroom drama Capital News and the 2011–2013 two season run of the ABC Family series The Lying Game.

Slater has stated that she pursued musical efforts even before doing movies. In the 1989 Patrick Dempsey romantic comedy Happy Together, she sang a medley of Broadway songs as well as other songs. In the 1994 movie Lassie, she also sang. For the soundtrack of the film Nowhere In Sight (2000), she contributed the song "The Detour."

In her next film, Slater was cast alongside Christian Slater and Yeardley Smith as Billie Jean Davy, a folk hero who styles herself as a modern-day Joan of Arc, in the film The Legend of Billie Jean (1985). Next, she appeared in two high-profile comedies, Ruthless People (1986) and The Secret of My Success (1987). More high-profile roles followed when she appeared in the independent comedy Sticky Fingers (1988) with longtime friend Melanie Mayron, City Slickers (1991) with Billy Crystal, the steamy A House in the Hills (1993) with Michael Madsen, and the action-crime drama No Way Back opposite Russell Crowe (1996). Other noteworthy performances were seen in films including 12:01 (1993), Betrayal of the Dove, and opposite Andy Richter in Seeing Other People (2004).

In 1985, DC Comics named Slater as one of the honorees in the company's 50th anniversary publication Fifty Who Made DC Great for her work on the Supergirl film.

During her career, Slater has revisited her 1984 role of Supergirl. She made a brief guest appearance on Seinfeld as a love interest of Jerry Seinfeld, who in reality is a huge fan of Superman. Slater was seen in a recurring role as Clark Kent's biological mother, Lara, on the TV series Smallville and as Supergirl's adoptive mother in the TV series Supergirl.

Slater made her acting debut in the ABC Afterschool Special Amy & the Angel, aired in 1982, alongside James Earl Jones, Meg Ryan, and Matthew Modine. This was also the only film in which she appeared exclusively as a brunette. In 1984, she played the title character, versus Faye Dunaway as Selena, in the TriStar release Supergirl. The film, directed by Jeannot Szwarc and including big name actors like Mia Farrow and Peter O'Toole, received mixed reviews, and was not a box-office success. The film was cited as a reason for publisher DC Comics killing off the original Kara Zor-El (1959) version of Supergirl in 1985, though a different Supergirl, Matrix, was created by DC Comics three years later. Slater's performance was not generally blamed.

Slater was born in Bethpage, New York, to a Jewish family. Her parents, Alice Joan (née Citrin), a lawyer and nuclear disarmament peace activist based in New York City, and Gerald Slater, a television executive, divorced in 1974. She has a brother, David, who is a lawyer in New York City. Slater attended Great Neck South High School and then transferred to the High School of Performing Arts from which she graduated in 1982. Despite common misconception, she is not related to actor Christian Slater, who played her brother in The Legend of Billie Jean.

Helen Rachel Slater (born December 15, 1963) is an American actress, singer and songwriter. She played the title role in the 1984 film Supergirl, and returned to the 2015 TV series of the same name, this time as Supergirl's adoptive mother. In the intervening years, she starred in several films including The Legend of Billie Jean (1985), Ruthless People (1986), The Secret of My Success (1987), and City Slickers (1991). She additionally found work as an actress in television, and stage projects, including three guest appearances on the series Smallville (2007–2010). She was a series regular for the two-season run (2011–2013) on the ABC Family series The Lying Game.
