Career background ↗Simon Callow’s Midsomer roles
Simon Callow’s Midsomer appearances are Dr Wellow in Dead Letters and Vernon De Harthog in The Curse of the Ninth. They are separate fictional people in separate investigations. A medical title in one credit does not place the actor among the recurring police pathologists, and the later role does not continue Wellow’s story. The titles, character names and cast sources below keep those distinctions explicit.
A two-case comparison can begin with whichever episode prompted your search, then move to the other appearance. The Casebook suggests noticing how each story establishes the character’s social circle before comparing the performance. That gives recognition of a returning actor a useful context without inventing a shared history between the parts. The episode descriptions below supply the respective premises and links to filming places. Callow’s wider theatre, film and television background is treated in the separate career section above; the Midsomer role list answers the narrower question of who he played, where the character belongs and which exact cases to watch.
