Making my way through the Prime Suspect series on Hulu right now. I was like 16 when it first started showing on TV and I don't remember much about it (other than the Harry Enfield show referring to writer Lynda La Plante as "Lynda La Plume De Ma Tante"). Feels dated in some ways- the gritty early 90s "hard hitting" material isn't quite so hard hitting now- but the feminist procedural angle is what makes it really interesting, and Helen Mirren is of course excellent.
Anyway, just finishing up season 3, and this thing is absolutely crammed with well known faces either at or near the start of their careers. Peter Capaldi (playing a trans woman, did not recognize him at first), a babyfaced Mark Strong, Ciaran Hinds, David Thewlis, Johnny Lee Miller, James Frain, a shockingly good Danny Dyer, etc. Good stuff.
