Zosia Budzinska is recommended for the role of 'Emily' because she has a feminine and fragile look along with acting experience. Nastya Nadezhdina is not preferred as her look seems too mature for the vulnerable young girl character. Hattie O'Donnell also isn't preferred despite looking the part because her acting skills are not as professional as Zosia's. For the role of the deliverer, John Winter is not preferred because while he looks the part, he lacks crucial acting skills. Vladimir also isn't preferred as the deliverer since although he has a shifty look, his body is too fragile for the part.
