Around 80 young people will stage a modern-day production of Robin Hood at the end of August as part of a Theatre Royal Bath project.
The youngsters, aged 12 to 18, will spend 13 days working with director Heidi Vaughan and the egg theatre's professional team to create the open-air performance.
They got together for the first time on Monday at Prior Park College, where they will transform an 18th century ball court into the Sheriff of Nottingham's castle.
Young people have created a wide range of classic and contemporary productions over the past 16 years as part of the project, which is called Storm on the Lawn.
Previous shows have included Dracula, Peter Pan and Shakespeare's The Comedy of Errors.
Producer Katherine Lazare said it was always a real team effort, with the backstage and production staff having just as an important role to play as those in the spotlight.
She said: "This year we have the largest ever young company in Storm history, with 78 participants either performing or backstage.
"They will all be working incredibly hard with the various production departments from choreography to stage combat, from costume to technical."
She added that the group's vision from the production was now starting to come together.
"The creative team has conceived such a fantastic and ambitious vision for this staging of Robin Hood and as rehearsals begin this week it is very exciting to see it start to come together."
All those involved will be hoping for dry weather over the next few weeks, so they can make the most of the open air space.
In previous years, heavy downpours have halted the performances.
Storm on the Lawn will perform Robin Hood from Wednesday, August 27 to Sunday, August 31 at the Ball Court in the grounds of Prior Park College.
Tickets are £13 for adults and £9 for students and children under 16.
