10 Things I Hate About You was one of the most iconic films to come out of the late '90s, and one of its stars, Gabrielle Union, decided to pay homage to that this week. The actress, who played Chastity, the ditzy best friend of Bianca Stratford ("I know you can be overwhelmed, and you can be underwhelmed, but can you ever just be . . . whelmed?") posted a photo of the cast on Instagram in honor of Throwback Thursday. The gloriously nostalgic photo shows Union posing with costars Julia Stiles, Heath Ledger, Joseph Gordon-Levitt, Larisa Oleynik, Andrew Keegan, and David Krumholtz in front of their massive Seattle high school. "Just a bunch of kids having the time of our lives up in Tacoma/Seattle ... 1st movie & an experience that I'll never forget," Union wrote. "The best/coolest/most generous group of people to share my 1st film experience. What a time man. ❤ and eternal light #RIPHeath #10thingsihateaboutyou #CanYouEverJustBeWhelmed." Can we please rewind back to the '90s?
