The Harry Potter movies are slowly but surely depleting a vital resource from the film industry: venerable British actors and actresses. Look at the number of renowed actors from the UK portraying characters in the series: Maggie Smith, Alan Rickman, Kenneth Branagh, Emma Thompson, Miranda Richardson, John Hurt, John Cleese, Julie Walters, Michael Gambon, Ralph Fiennes, Gary Oldman, Dawn French, Julie Christie ... the list is impressive and seemingly unending. Imelda Staunton has just been cast as Dolores Umbridge in Harry Potter and the Order of the Phoenix. Stephen Fry hasn't appeared in the movies yet, but he's been voicing the narrator in the video games.
I am worried that before the series is finished, the Harry Potter casting directors will have to recruit amateurs or, perish the thought, Americans. Can you imagine Renee Zellweger or Uma Thurman trying to mimic a British accent? Perish the thought.
After the jump, I've listed the top seven remaining well-known British charactor actors that I suspect may be sucked into future Harry Potter films, along with the possible roles they might play.
