No, the original PlayStation (PS1) cannot play movies directly. It lacks a DVD or Blu-ray drive—it's a CD-ROM-based game console. The laser only reads CD-ROM (data), CD-DA (audio), and PS1 game discs (which are specialized CD-ROMs).
For movie playback, use a dedicated DVD/Blu-ray player, a streaming stick (Roku, Fire TV, Chromecast), a modern console (PS4/PS5, Xbox Series X/S), or a smart TV. The PS1's video capabilities are essentially non-existent by any modern standard.
