How many minutes long is the extended edition of The Return of the King?

How to get close to this number

Start from the theatrical cut, which most people remember as being long, and add the extension. Extended editions of these films add roughly a third again to the running time. A film already well over three hours, plus a third, puts you comfortably in the right region without needing to recall the exact minute count.

The comparison in the explanation is the useful one: a full extended trilogy marathon outlasts a long-haul flight. That reframes the number from a piece of film trivia into something with a physical cost — it is a commitment measured against a day rather than against an evening, which is exactly how the people who attempt it describe it.

Runtimes are less fixed than they look. A film exists in theatrical, extended and sometimes broadcast versions; different regions have had different cuts; and published durations may or may not include the credits, which in this case run unusually long. When a runtime is quoted, the edition is doing as much work as the number, which is why this one is stamped with the home video release.
