Erika Jane Christensen was born on August 19, 1982, in Seattle, Washington, to Kathy Hendricks and Steven Christensen. Although born in Seattle, she was raised in the Los Angeles area. Her interests extended beyond acting to singing and dancing, but by the age of 12 she had decided that acting was the direction she wanted her life to take.

Christensen's first professional work included a McDonald's television commercial, followed by an appearance in Michael Jackson's music video for “Childhood.” It was an impressive introduction to the entertainment business for somebody who had barely entered her teenage years.

Her first substantial movie opportunity arrived with the 1997 comedy Leave It to Beaver, based on the classic television series. Christensen played Karen, Wally Cleaver's romantic interest. She was only in her early teens, but the role placed her prominently in a major studio production and helped establish her as a young actress to watch.

Television work followed rapidly. Christensen made appearances in several prominent series during the late 1990s, including Frasier, The Practice, 3rd Rock from the Sun, Touched by an Angel and Nothing Sacred. Her performance on Nothing Sacred brought her a YoungStar Award nomination. She also appeared in the wonderfully titled 1999 Disney Channel movie Can of Worms.

Then came Traffic.

Steven Soderbergh's 2000 crime drama Traffic examined America's drug trade through several interconnected stories and featured an enormous ensemble including Michael Douglas, Benicio del Toro, Catherine Zeta-Jones, Don Cheadle, Dennis Quaid and Topher Grace. Christensen played Caroline Wakefield, the teenage daughter of Michael Douglas's character, Robert Wakefield, a judge appointed to lead the government's campaign against illegal drugs.

There was one rather substantial problem with that appointment: Robert's own daughter was struggling with drug addiction.

Christensen's performance was deliberately uncomfortable and unglamorous. Caroline's descent into addiction gave the movie's enormous political subject a painfully personal dimension. The government's newly appointed drug czar could discuss national strategy all he liked, but the crisis was already sitting at his own dinner table.

The performance became Christensen's breakthrough. She won the MTV Movie Award for Breakthrough Female Performance and received recognition from the Young Hollywood Awards. More significantly, she shared the Screen Actors Guild Award for Outstanding Performance by a Cast in a Motion Picture with the ensemble of Traffic.

Suddenly, the teenage actress who had appeared in a McDonald's commercial only a few years earlier was part of the cast of an Academy Award-winning film.

Christensen followed Traffic with a very different sort of unsettling teenager in the 2002 thriller Swimfan. She played Madison Bell, a new student who becomes dangerously obsessed with a high-school swimming star played by Jesse Bradford. What begins as an affair rapidly turns into stalking, manipulation and violence.

It was not exactly an advertisement for joining the school swim team.

The movie gave Christensen another highly visible leading role and demonstrated her ability to portray a character who could move from charming to deeply disturbing with alarming speed. Interestingly, Christensen really is a swimmer—something that made at least one aspect of Madison Bell considerably less fictional.

Her film career continued with The Banger Sisters in 2002, starring Goldie Hawn and Susan Sarandon, followed by The Perfect Score in 2004. The latter featured a young ensemble that included Chris Evans and Scarlett Johansson, years before either became permanently associated with superhero costumes.

In 2005, Christensen appeared opposite Jodie Foster in the airplane thriller Flightplan. She continued balancing movie roles with television work, gradually building the kind of résumé that allowed her to move between genres rather than becoming permanently attached to the intense young women she had played earlier in her career. IMDb lists more than 60 acting credits across her career.

Her next defining role arrived in 2010 when NBC introduced Parenthood.

Based loosely on Ron Howard's 1989 film of the same name, the television series followed several generations of the Braverman family as they navigated marriages, children, careers, illnesses, financial problems and the general complications created whenever a large family knows absolutely everything about everybody else's business.

Christensen played Julia Braverman-Graham, the youngest daughter of Zeek and Camille Braverman and sister to Adam, Sarah and Crosby. Julia was an ambitious attorney married to Joel Graham, played by Sam Jaeger.

Julia initially appeared to have much of her life carefully arranged. She was professionally successful, married and raising a daughter. This being Parenthood, naturally none of those conditions were permitted to remain uncomplicated for very long.

Over six seasons, Julia's story explored the competing demands of career and family, fertility struggles, adoption, parenting, marital difficulties and eventually the serious strain placed upon her relationship with Joel. Christensen was given some of the show's most emotionally difficult material, particularly as Julia's carefully controlled life became increasingly unpredictable.

That was one of the strengths of Parenthood. The series rarely required villains. Most of its problems came from ordinary people loving each other while simultaneously possessing the remarkable human ability to make everything much more complicated than necessary.

Christensen's Julia fit beautifully within that approach. She could be determined and practical while also insecure, frustrated and occasionally wrong. Rather than presenting Julia as the family's permanently successful attorney, the series allowed her to stumble professionally and personally.

The ensemble included Craig T. Nelson, Bonnie Bedelia, Peter Krause, Lauren Graham, Dax Shepard, Monica Potter, Mae Whitman and Sam Jaeger, among many others. The chemistry among the cast helped Parenthood develop a particularly devoted following during its run from 2010 until 2015.

The series became so closely associated with Christensen that for many viewers Julia Braverman-Graham ultimately surpassed Caroline Wakefield as her signature role. Traffic had demonstrated what she could accomplish in an intense dramatic film; Parenthood gave her six seasons in which to develop a character gradually.

After Parenthood ended, Christensen continued working steadily in television and film. She starred in the short-lived ABC crime drama Wicked City in 2015 and later appeared in the 2017 film The Case for Christ, based on Lee Strobel's book. She also served as an associate producer on the latter project.

Christensen subsequently returned to series television in ABC's Ten Days in the Valley and later played Detective Angie Polaski in the ABC crime drama Will Trent. The latter role brought her back into a darker television world, although this time she was investigating troublesome people rather than playing one.

Her career has also expanded behind the camera. IMDb credits Christensen not only as an actress but as a producer and director, reflecting a professional life that has gradually broadened beyond acting alone.

Away from acting, Christensen married cyclist Cole Maness on September 5, 2015. The couple have two children.

One unusual aspect of Christensen's childhood is that she was homeschooled by her parents rather than attending public school. That meant some of her acting roles involving conventional school life required a little extra research. Hollywood occasionally demands that actors learn sword fighting, horseback riding or complicated accents. Christensen sometimes had to research something equally foreign: going to school every morning.

Looking across her career, Christensen's longevity is perhaps more impressive than any single performance. She entered professional entertainment as a child, successfully made the notoriously difficult transition into adult roles and then found another major television success years after the movie that first brought her widespread attention.

Traffic showed audiences that Erika Christensen could handle demanding dramatic material. Swimfan demonstrated that she could make viewers extremely nervous. Parenthood allowed her to build a complicated character across six seasons, while her subsequent television work has kept her firmly in the public eye.

And after spending six seasons as a member of the Braverman family, almost anything Hollywood throws at her should be manageable.

Once you've survived that many family dinners, you've been trained for practically everything.
