The person playing Kneale will be able to use their voice in such a way as to portray both:
Kneale in the present day – age 65, highly intelligent, jaded, impatient, possessed of terrible secrets
Kneal in the 1980s – age 25, intelligent, curious, optimistic, excitable in the presence of new mysteries
Note: we are working on digital techniques that may enable us to support the voice actor in performing out of their natural age range, but the less filtered the voice is, the better it will sound.
We also want whoever plays Kneale to help shape the character – and by extension the show a whole – and create a voice for him. To this end, it is crucial that anyone who is interested in the part is able to adapt the script to fit Kneale’s voice as if it were their own, and thus produce a totally believable performance.
