The Interstellar meme primarily centers on the high-stakes emotional scenes featuring Matthew McConaughey as Joseph Cooper. The most famous variation, 'Cooper Crying,' comes from the scene where he watches decades of missed video messages from his children, capturing a sense of profound loss and regret. Another popular version is the 'Tesseract' scene, where Cooper desperately shouts at his past self through a bookcase. These templates are widely used to represent nostalgia, the pain of seeing one's past mistakes, or the overwhelming feeling of time passing too quickly. Since the movie's release in 2014, these moments have become shorthand for cinematic sadness and existential dread across social media.
