Star Wars: Episode III – Revenge of the Sith runs about 2 hours 20 minutes (140 minutes) for the standard theatrical version.

A few quick clarifications for context:

  • The commonly listed runtime on major movie databases is 2h 20m.
  • Some fans note that without end credits , the movie itself is roughly 2h 14m of story.
  • Behind‑the‑scenes trivia mentions that George Lucas’s original assembly cut was close to 4 hours before being edited down for theaters.

So, if you’re planning a watch, setting aside about 2 hours and 20 minutes will comfortably cover Star Wars Episode 3.
