12 Harry Potter Actors Who Were Replaced In The Sequels
3. Jessica Hynes - Mafalda Hopkirk
The Replacement: Sophie Thompson
You could be forgiven for not knowing that Jessica Hynes - recognisable to British comedy fans for the excellent Spaced - was even in Harry Potter. She was actually only involved briefly, lending her voice to Mafalda Hopkirk in The Order Of The Phoenix.
The character isnt actually seen on screen, but its Hynes voice that expels Harry Potter for his improper use of magic at the start of the film.
For The Deathly Hallows, Mafalda was required to be seen on screen as it is she who Hermione Grainger pretended to be to access the Ministry. For that film, David Yates brought in fellow British comedy actor Sophie Thompson.
