How old is Morse in 1967?
Shaun Evans was 36 during series 4 but is clearly playing someone much younger, certainly no older than 30.
How much do we know about Morse after he dropped out of Oxford?
The pilot is set in 1965 I would guess Morse would be mid to possibly late twenties then. There was talk about learning Russian whilst in the secret services before joining the police, I can't remember but was there also mention of the army?
