If you are looking at the release (specifically the acclaimed Criterion Collection edition), here is what makes this particular version and film so significant: The "Uncut" Vision
Set in a then-future 1999, it follows Claire Tourneur (Solveig Dommartin) as she pursues a mysterious stranger (William Hurt) across the globe while a nuclear satellite threatens to crash into Earth.
For decades, audiences only saw a "butchered" 2.5-hour theatrical version that Wenders famously called the "Reader’s Digest" cut. The (nearly 5 hours) restores the film's intended rhythm, humor, and depth.
