Fan Casting Dr. Elwin Ransom in Out of the Silent Planet

Ransom is tall, but a little round-shouldered, about thirty five to forty years of age, and dressed with that particular kind of shabbiness which marks a member of the intelligentsia on a holiday. He might easily be mistaken for a doctor or a schoolmaster at first sight, though he has not the man-of-the-world air of the one or the indefinable breeziness of the other. In fact, he is a philologist, and fellow of a Cambridge college. (Same character as https://www.mycast.io/stories/that-hideous-strength/roles/dr-elwin-ransom/165426)
