(CNN) Zooey Deschanel and Joseph Gordon-Levitt look like they haven't aged a day, but it's been a decade since the two starred in "(500) Days of Summer."

On Thursday, Deschanel, 39, took to Twitter to remind fans of the movie. "It's been 3652 days since #500DaysofSummer," she wrote alongside a shot of her and Gordon-Levitt, whose Tom was so lovesick over Deschanel's character, Summer.

Gordon-Levitt, 38, also remembered the special day, writing on Twitter, "Today's the 10 year anniversary of (500) Days of Summer. Where did all the time go, @ZooeyDeschanel???"

"Let's do it all again," she wrote. "Every ten years!"
