Byrne told RadioTimes.com the Season 6 send-off has a run time of 81 minutes.
“It’s such a Peaky thing to do for the last hurrah. It’s the 10:22 news for one night only,” Byrne said. “It feels very, very different to the rest of the season. It feels very, very different to anything we’ve done before. It’s very epic in scope. It feels like a film – it’s a kind of dry run for the feature film.”
Show creator Steven Knight also told RadioTimes.com that the upcoming movie will be an “untold story that happened in the Second World War, which the Peakys are going to be involved in”.
Byrne has previously responded to criticism about the change in the show’s tone, especially for the last season.
