The Crown Quiz

Everything about the cast of the Netflix historical drama, scoped to Seasons 1 through 4. The answer is always the ACTOR, never the character. In vs out: every actor billed in the opening credits across those four seasons is in, including both halves of the show's famous mid-run recast; recurring and guest performers are out, and so are the actors who took over the roles from Season 5 onward. Six roles are played by two different actors inside this range, and both are in the set. Cast sourced in billing order from Wikipedia's main-cast tables, corroborated against Wikidata. One note on the trivia: this is a drama about real people, so every question here is about the series itself (casting, production, awards, music, locations). Nothing in this set is a claim about history.
