New Hogwarts Staff

British actress Imelda Staunton announced on TV show This Morning that she has been cast as the malicious Ministry of Magic employee and new Defence Against Dark Arts teacher Dolores Umbridge in the fifth installment of the Harry Potter movies, Harry Potter and the Order of the Phoenix.

Staunton says she hasn't yet received a script but expects to start work on the flick sometime in the new year.

Daniel Radcliffe, Emma Watson and Rupert Grint are all set to return for the next installment, as is Jason Issacs as Lucius Malfoy and Ralph Fiennes as Lord Voldemort.

British director David Yates helms for a June 2007 release.
