At Supanova Melbourne 2021 in a back stage interview, McIntyre stated that he was pleased with the ending of the series. He believes that this ending was the best was for the hero (Spartacus) to win (by defeating Crassus) but at the same time, keeping true to historical events.

The Spartacus actor also went on to say that the series did end with an open ending, hinting a spin-off was to come. This was due to there being serious plans put in place for a spin-off, which sadly, never went into production.
However, McIntyre did say that there’s always still a hope that a spin-off is still possible in the future although, he won’t be part of it. You can check out the full interview with McIntyre at Supanova Melbourne 2021 in the video below.
