Born into a family of thespians--parents Roger and Sally were both stage actors, maternal grandparents Oliver and Linda Bridges ran the Reading Repertory Theatre, and uncle Robert Bridges was a fixture in London's West End theatre district--Kate came into her talent at an early age. She scored her first professional gig at 11, dancing opposite the Honey Monster in a commercial for a kids' cereal. She started acting lessons around the same time, which led to formal training at a performing arts high school. Over the next few years she appeared on stage regularly and landed a few bit parts in sitcoms. Her first big break came at age 17, when she was cast as an obsessive adolescent in Heavenly Creatures (1994). The film, based on the true story of two fantasy-gripped girls who commit a brutal murder, received modest distribution but was roundly praised by critics.

Still a relative unknown, Winslet attended a cattle call audition the next year for Ang Lee's Sense and Sensibility (1995). She made an immediate impression on the film's star, Emma Thompson, and beat out more than a hundred other hopefuls for the part of plucky Marianne Dashwood. Her efforts were rewarded with both a British Academy Award and an Oscar nomination for Best Supporting Actress. Winslet followed up with two more period pieces, playing the rebellious heroine in Jude (1996) and Ophelia in Kenneth Branagh's Hamlet (1996).

The role that transformed Winslet from art house attraction to international star was Rose DeWitt Bukater, the passionate, rosy-cheeked aristocrat in James Cameron's Titanic (1997). Young girls the world over both idolized and identified with Winslet, swooning over all that face time opposite heartthrob Leonardo DiCaprio and noting her refreshingly healthy, un-emaciated physique. Winslet's performance also garnered a Best Actress nomination, making her the youngest actress to ever receive two Academy nods.

After the swell of unexpected attention surrounding Titanic (1997), Winslet was eager to retreat into independent projects. Rumor has it that she turned down the lead roles in both Shakespeare in Love (1998) and Anna and the King (1999) in order to play adventurous soul searchers in Hideous Kinky (1998) and Holy Smoke (1999). The former cast her as a young single mother traveling through 1960s Morocco with her daughters in tow; the latter, as a zealous follower of a guru tricked into a "deprogramming" session in the Australian outback. The next year found her back in period dress as the Marquis de Sade's chambermaid and accomplice in Quills (2000).

Off camera, Winslet is known for her mischievous pranks and familial devotion. She has two sisters, Anna Winslet and Beth Winslet (both actresses), and a brother, Joss. In 1998 she married James Threapleton, whom she met on the set of Hideous Kinky (1998); the pair had a daughter, Mia, in October of 2000.
