The line comes from Star Wars: Episode IV - A New Hope, released in 1977, where Obi-Wan Kenobi speaks to Luke Skywalker during his early training and the attack on the Death Star. It became one of the franchise's most quoted phrases and spread far beyond the film into posters, parodies and early internet soundboards. Fans still pair it with other iconic moments, including Darth Vader scenes, because the calm instruction sums up the Force itself: trust, focus and letting go at the critical moment.
