Released in 1999, teen rom-com '10 Things I Hate About You' was based on the William Shakespeare play 'The Taming of the Shrew' and made stars out of Julia Stiles, Joseph Gordon-Levitt and the late, great Heath Ledger with its complex, hilarious and heartfelt tale of dating gone awry. Fifteen years later, we revisit the cast of this modern classic and see what they're up to now.

Then: Julia Stiles played Kat Stratford, the feminist, headstrong elder of the Stratford sisters who is happy with her father's rule that her younger sister Bianca cannot date until Kat does. Stiles previously appeared in 'The Devil's Own' with Harrison Ford and Brad Pitt.

Now: Stiles went on to appear in the teen films 'Down to You,' 'Save the Last Dance' and 'O.' She also appeared in the 'Bourne Identity' trilogy, 'Mona Lisa Smile' and the remake of 'The Omen.' She took a break from appearing in films for a few years, during which time she had a recurring role on 'Dexter.' Stiles re-emerged with roles in 'Silver Linings Playbook,' 'It's a Disaster,' 'Girl Most Likely' and 'Closed Circuit,' and can be seen next in 'Out of the Dark.'

Gordon-Levitt was best known at the time for his role on '3rd Rock from the Sun,' on which Larisa Oleynik also played his love interest.

Now: Gordon-Levitt has become a major household name, and has since appeared in films like Rian Johnson's indie 'Brick,' reuniting with the director in 2012 for 'Looper.' He also starred in '(500) Days of Summer,' 'Inception,' '50/50,' 'The Dark Knight Rises' and 'Premium Rush.' Gordon-Levitt recently made his directorial debut with 'Don Jon,' a film in which he also starred alongside Scarlett Johansson, and he can be seen next in 'Sin City: A Dame to Kill For,' a film for which he turned down the role of Star-Lord in Marvel's 'Guardians of the Galaxy.'

Then: Heath Ledger beat out Josh Hartnett and Ashton Kutcher for the role of rebellious bad boy Patrick Verona, whom Cameron convinces to date Kat in an effort to get Kat and Bianca's father to allow Bianca to date. Ledger was a then unknown actor in the US who previously had a role on the Australian series 'Home and Away.' '10 Things About You' was his first major film role.

Now: Ledger's career blew up after that, and he starred in films like 'The Patriot,' 'A Knight's Tale,' 'Brokeback Mountain' and 'I'm Not There.' Ledger tragically passed away in 2008 at the age of 28, but he left behind a legacy that included an incredibly memorable performance as the Joker in Christopher Nolan's 'The Dark Knight' -- a performance that earned him a posthumous Oscar for Best Supporting Actor. His final film role was in Terry Gilliam's 'The Imaginarium of Doctor Parnassus,' which was released in 2009.
