*shows up randomly to recommend Attack the Block to anyone who hasn't seen it*

I think that was the first thing I saw Jodie Whittaker in - or at least the first thing I remembered her from, since I watch a LOT of costume drama and must have seen her in Cranford and Tess of the d'Urbervilles. She's really good in it, and deals well with aliens (a plus for her new job) - and of course, it also stars baby John Boyega.
