Peaky Blinders star Sophie Rundle has admitted she's terrified of ruining the show's ending for its longstanding fans as she's "such a blabbermouth".
The BBC One period gangster drama begins its final season this Sunday and has managed the incredible feat of keeping the vast majority of storylines to come under wraps, despite huge interest and anticipation.
But Rundle, 32, told Metro that she was worried about spoiling things for fans who have had a long wait to see how the Shelbys' tale plays out after production was delayed by the coronavirus pandemic.
The Ada Shelby actor said of receiving the final scripts: "It’s always really exciting! It’s always really terrifying that you know something that loads of people want to know, and I’m such a blabbermouth, I can’t tell everyone what happens."
She continued: "But they were great, I was pregnant at the time and then [the team] were like, 'Look, these are your scenes all put together just to make it easier for you.'
"Then they sent me all the scripts, and it’s just so much fun to read them but you get all the scripts together. It’s like a novel. It’s been brilliant!"
Series five ended on a cliffhanger with a gun pointed at Tommy Shelby's (Cillian Murphy) head, but while it's obvious that he survives as he goes on to star in series six, the other details have been kept secret.
Rundle, who admitted she couldn't bring herself to watch her own performances on screen, joked that some of the twists and turns may also be a surprise to her as she was in the fog of having a newborn baby when filming happened.
She gave birth to her son, her first child, over the Easter weekend in 2021 not long before Peaky Blinders began filming.
The star said that she "didn't really remember a lot about the time when we were filming" and laughed that finding out what happened in the drama would be a "revelation" for her too.
Peaky Blinders series 6 begins tomorrow (Sunday) at 9pm on BBC One.
