The daughter of director Stephen Gyllenhaal (Waterland [1992]) and screenwriter Naomi Foner (Running on Empty [1988]), and the sister of hot young Hollywood heartthrob Jake Gyllenhaal (Donnie Darko [2001], The Good Girl [2002], Moonlight Mile [2002]), Maggie Gyllenhaal seems to have all the makings of a successful young starlet with her Tinseltown background and curiously unique beauty. Born in 1977, Gyllenhaal got some early screen breaks thanks to roles in such Stephen Gyllenhaal films as Waterland (1992) and Homegrown (1998). Soon graduating from Columbia University with an English degree, pretty Gyllenhaal continued to refine her acting skills on the stages of New York and London theaters in such productions as The Tempest and The Butterfly Project. Her ascent into the collective film conscience continued with a humorous turn in director John Waters' anarchic Cecil B. Demented and alongside younger brother Jake in the surreal teen fantasy Donnie Darko (2001). Soon gaining more prominent roles alongside such hot Hollywood actors as Drew Barrymore (Riding in Cars With Boys [2001]) and Josh Hartnett (40 Days and 40 Nights [2002]), Gyllenhaal would turn up later in 2002 in eccentric director Spike Jonze's sophomore effort, Adaptation. Her supporting roles offering but a glimpse into her engagingly offbeat talent, Gyllenhaal truly came into her own with her breakthrough performance as a mentally unstable secretary in director Steven Shainberg's 2002 dark comedy Secretary. Cast opposite former '80s wonder boy James Spader, Gyllenhaal displayed a careful balance of unshielded vulnerability and mild sadomasochism as the film's troubled lead. Nominated for numerous awards including a Golden Globe and Independent Spirit for Best Actress, Secretary found the disarming actress branded the "it" girl to watch for in the coming years. While subsequent supporting performances in such films as Confessions of a Dangerous Mind, Casa de Los Babys, and Mona Lisa Smile may not have offered fans the large dose of Gyllenhall that they sought after Secretary, audiences could see her in a starring role opposite John C. Reilly in the 2004 George Clooney/Steven Soderbergh-produced remake Criminal. Gyllenhaal kept up her status as an independent film icon in 2005 with major parts in The Great New Wonderful and earning praise for her work in Don Roos' Happy Endings where she got to show off her vocal talents performing a selection of Billy Joel songs. 2006 would be a very busy year for the actress. She co-starred in Oliver Stone's 9/11 film World Trade Center, gave an award winning performance as a drug addict in SherryBaby, and lent her voice to the Steven Spielberg produced animated film Monster House. That same year she announced that she was expecting her first child with her longtime boyfriend actor Peter Sarsgaard.
