You know what movie - or series of movies - have a perfect cast? Or should I say the perfect SUPPORTING cast? Except for the 3 young leads, my vote goes for The Harry Potter films. What other movie is able to gather up the talents of some of the very best of English thespians like Emma Thomson, David Thewlis, Gary Oldman, Maggie Smith, Michael Gambon, Richard Harris, Imelda Staunton, Alan Rickman, Julie Walters, Kenneth Branagh, Helena Bonham Carter, Ralph Fiennes, Jason Isaacs, Brendan Gleeson, Miranda Richardson and I think they also threw Julie Christie in somewhere. These people are the best thing about those movies. One would think Harry, Ron and Hermoine would've picked up a thing or two from them by now, but...
(I know, I know, Gleeson and Branagh are Irish)
