Visionary director Michel Gondry's comical and poignant look at breakups, breakdowns and breakthroughs has endured as a classic love story and prescient sci-fi tale. The film, which stars Jim Carrey and Kate Winslet as its eternal lovers, begins on Valentine's Day, 2004.

Joel (Carrey) is stunned to discover that his ex-girlfriend, Clementine (Winslet), has had their tumultuous relationship erased from her mind. Out of desperation, he contacts the inventor of the process, Dr. Howard Mierzwiak (Tom Wilkinson), to get the same treatment. But as his memories of Clementine begin to fade, Joel suddenly realizes how much he still loves her.

Eternal Sunshine of the Spotless Mind was released in theaters on March 19, 2004. It was a box office success, won the Oscar for Best Original Screenplay, and now 20 years later, is considered one of the greatest films of the 2000s.
