Flashback to the 90s! Joseph Gordon-Levitt has reunited with some of the cast of 10 Things I Hate About You to celebrate the movie’s 15th anniversary.

The teen flick – based on Shakespeare’s The Taming Of The Shrew and featuring the late Heath Ledger’s fantastic rendition of Franki Valli’s I Love You Baby in the middle of a high school football field – was released in 1999.

Joseph joined screenwriter Karen McCullah and co-stars Andrew Keegan, David Krumholtz and Susan May Pratt to celebrate being part of the hit movie, and Karen tweeted a picture of them all together.

Sadly missing from the reunion were leading ladies Julia Stiles and Larisa Oleynik, along with Gabrielle Union and of course the late Heath.

The Australian actor made his name in the hit rom-com and went on to become the critically acclaimed star of films including Brokeback Mountain and The Dark Knight, before dying at the age of 28, from accidental intoxication of prescription drugs.

In an interview with Us Weekly last month, Julia, who played tomboy Kat Stratford, who fell for Heath’s character in 10 Things I Hate About You, said the best part about working on the film was “how well the cast got along”.

“It was such a fun summer and such a pure experience of working on a movie where we were all – this was our first big break,” she said. “We were really open and invested and it was really fun being in Seattle.”

All together now, “I love you BAAAAABY and if it’s quite alright….”
