Tombstoneis often considered one of the greatest Westerns ever made, and for good reason. This is a movie that features a star-studded cast, including Kurt Russell and Val Kilmer, plenty of intense fights, and some surprisingly emotional scenes between its hardened gunslingers. While there's no shortage of moments that make Tombstone a worthwhile watch, it's the final narration by Robert Mitchum — especially the final three words — that cements its place in the pantheon of great Westerns.
