But now HBO has confirmed a small - yet significant - new detail: just how long the final season is actually going to be.
Another pointed out that HBO has counted "making of material" shown at the end of the episodes in their official runtimes, raising questions about how much of these times are devoted only to the story.
Similar to the debut episode, the 21st will air for 58 minutes.
As previously reported, Season 8 will kick off April 14 with a 54-minute episode. Episode four, Sunday May 5, is back down to an hour and 18 minutes, but episode five on Sunday, May 12 is back up to an hour and 20 minutes. Make sure you've cleared out your Sunday nights for the following dates, because it's unlikely you'll have time to do anything other than watching the feature-length episodes and talking about them for hours afterwards.
Episode 6, the series finale, airs Sunday, May 19 at 9 p.m. E.T.More news: All American diplomats have left Venezuela, says Pompeo

HBO has confirmed Game of Thrones' final supersized episodes, including three that hit the 80-minute mark.
From that point, the lengths are edging closer to film length.
Either way, though, Game of Thrones fans in Ireland will have to wait until the following day to be able to catch up on what's happening in the world of Westeros. Well, it turns out that isn't quite the case - but there will be a fair few longer episodes in Game Of Thrones' final run.
If you're not up for staying up super late/getting up super early, the episode will also be airing on Sky Atlantic and NOW TV at 9pm that evening.
