Cate Blanchett and Russell Crow take direction from Ridley Scott
Actress Sara Poyzer, from Calverton, has been helping to make the new Robin Hood film more authentic.
The West End star was hired to record background voices of persecuted villagers to give the sound more depth.
Sara had to say lines like: "Please don't kill us! Please don't burn us! [and] God help us!"
The accents of former Robin Hoods have been ridiculed but Sara said she was "really impressed" by Russell Crowe's stab at the Nottinghamshire accent.
She said: "It's one of the hardest to get right, people tend to go into Yorkshire. It's a weird sound.
"It's been helpful to me, it got me my first radio job, my first TV job and my voiceover agent."
She was pleased the film's director Ridley Scott was making the leads speak with a local voice. Adaptations starring Kevin Costner, Errol Flynn and even Walt Disney characters have failed to tackle the Nottingham dialect.
Sara's voiceover work on the Robin Hood film is part of a process called automated dialogue replacement (ADR).
Sara Poyzer has added her voice to several Hollywood blockbusters
"Basically, in big movies and some television series, supporting artists are invited to a studio to bulk out the sound to make it more authentic," said the 39-year-old.
"We watch a scene and are asked to do lines that are appropriate. Sometimes you lip-sync. It's a fascinating extra job actors do that you don't hear about that often."
Although the stars of Robin Hood will now speak with a local accent it might still sound strange to some Nottinghamians.
"The accent man said I had to base it on a Rutland sound because modern Nottingham is much flatter."
Sara has not seen the whole of the cut film but was impressed with what she has seen so far.
"The bits that I saw were quite violent and visceral but all the better for it. It felt much more real."
Robin Hood is not the first big Hollywood film Sara Poyzer has added her vocal talents to. In the last 12 months she has contributed to The Imaginarium of Doctor Parnassus and Tim Burton's re-imagining of Alice in Wonderland.
"I was doing something called toadying," she said of the Alice film. "To toady is what people do to members of the royal family. It's basically being obsequious. I was doing a lot of that to Helena Bonham-Carter."
Robin Hood is due to be released in cinemas on 12 May, 2010.
