With the fifth instalment of the Harry Potter films in the making, the roll-call of famous names popping up alongside the boy wizard just seems to grow and grow.
The latest star to sign up for a part in the fantastical world of Hogwarts is Helena Bonham Carter.
She will play Bellatrix Lestrange in Harry Potter And The Order Of The Phoenix.
In case you're not au fait with the dramatic persona in JK Rowling's smash hit books, let us explain.
Bellatrix is the cousin of dark hero Sirius Black (played by Gary Oldman) but she is also a follower of Harry's nemesis, Lord Voldemort.
Helena is no stranger to dark and magical stories, what with starring in some of her partner Tim Burton's films.
She lent her voice to The Corpse Bride and starred in Charlie And The Chocolate Factory.
The latest Harry film will see Daniel Radcliffe, Rupert Grint and Emma Watson reprise their roles as teen wizards Harry Potter, Ron Weasley and Hermione Granger.
While other new faces will include Vera Drake star Imelda Staunton as Dolores Umbridge, Hogwarts' student-hating High Inquisitor.
Helena and Imelda join a host of big names who have stepped up for the children's tale - Robbie Coltrane, Ralph Fiennes, Alan Rickman, Emma Thompson and Julie Walters to name only a few.
Harry Potter And The Order Of The Phoenix is out in 2007.
