Said breakdown includes seven leading characters:
1. Late-teen female, independent, good sense of humour, fit.
2. Young twenty-something male, witty and smart, fit but not traditionally good looking.
3. A late twentysomething male, fit, handsome and confident.
4. Seventy-something male, with strong opinions and tough demeanour. Also doesn’ t need to be particularly fit.
5. A second young female, also late teens, tough, smart and fit.
6. Forty something male, fit, military type.
7. Thirtysomething male, intellectual. Apparently doesn’t need to be fit.
