Just rewatching Our Friends In The North (one of the greatest TV series of all time) and it has David Bradley (Walder Frey) as a political activist, Donald Sumpter (Maester Luwin) as a police chief and Peter Vaughn (Maester Aemon) as the dad of one of the main characters. This is apart from the fact that it also stars James Bond (Daniel Craig) and Doctor Who (Christopher Ecclestone).
