Harriet Slater
Harriet Slater is an actor, born 1994.
Harriet Slater is an English actress from Leicester who joined a local youth theatre group at six and has spent her twenties working the period-drama and genre circuit. Tatler named her a Bright Young Thing in 2023, the sort of listing that usually turns up a year before the jobs get larger, and in her case it did.
Pennyworth gave her Sandra Onslow, tangled up with the young Alfred in a show that treats Batman's butler as a working-class Londoner with a past rather than a punchline, and it is the role that shows what she does best: warmth with a hard edge kept visible underneath it.
Belgravia: The Next Chapter and Outlander: Blood of My Blood are the period work, and the second is the biggest job she has had. Playing Ellen MacKenzie in a prequel to a series with an audience that committed means every choice gets examined by people who know the source better than the production does. On film she is Fran in Indiana Jones and the Dial of Destiny, a small part inside an enormous machine, and Haley in the horror picture Tarot. Fall 2: Deadpoint is listed here for 2026. The trajectory is a steady one, and it is currently pointing up.

Where to start with Harriet Slater
For a proper introduction, start with Pennyworth: The Origin of Batman's Butler, which ran from 2019 to 2022 and is a far odder, funnier show than the DC branding suggests.
Go next to Outlander: Blood of My Blood for the largest role on the list, and note that it plays perfectly well without the parent series if you have never seen it. Belgravia: The Next Chapter is the polite period option, all drawing rooms and social knives. Indiana Jones and the Dial of Destiny is the biggest production she has been near and the smallest thing she does in it. Tarot is the horror entry, and Fall 2: Deadpoint is the one still ahead of her.
