For the Falmouth-based scenes around five hundred extras are needed. The casting sessions are free to attend and are open to those aged 16 and over. A casting for children is set to be held at a later date. The roles will be paid for and those involved may be asked to have their hair cut short. The casting unit is particularly interested in those from the forces, fire brigade and RNLI and a number of film crew support staff may also be required. Anyone wishing to take part can also upload their details to www.maddogcasting.com.
