Gordon-Levitt took to Twitter Sunday to to share a black-and-white photo of him and his co-stars Heath Ledger, Julia Stiles, David Krumholtz, Andrew Keegen and Susan May Pratt hanging out in a couple of director's chairs during a break in filming in what appears to be the movie's iconic prom scene.
The photo, which also features director Gil Junger, shows the cast all dressed up in tuxedos and gowns as they smiled and posed for the camera.
“You're kidding!" he said to ET’s Lauren Zima, reacting to how more than two decades have passed since the film’s release.
The experience was a transformative one for Gordon-Levitt and much of the cast, who still remain in contact today.
"We would just hang out with each other and, like, listen to music," recalled Gordon-Levitt, who shared that he's still in touch with Krumholtz and Larisa Oleynik (who played Bianca) in the film.
“David Krumholtz [and I] -- we're always in touch,” he added.
Stiles and Gabrielle Union had similar memories of the camaraderie on set while speaking with ET during the film's 20th anniversary in 2019.
"It was just such a special summer, where all the actors were so young and open hearted," Stiles said. "We were all really good friends."
"We spent all of our downtime together and loved it, [and] perhaps I got some fake IDs," Union shared with a laugh. "It was just such a special, special time, and I could never recreate that."
For Union, shooting 10 Things I Hate About You was such an incredible experience, she told ET that it sort of set an unreasonable expectation for what being on movie sets would be like for the rest of her career.
"We had a great, great time, I remember thinking all movie making was going to be like that," she recalled. "[But] I've never had an experience quite as special as 10 Things I Hate About You."
