After my thoughts on Graham Onions' resemblance to Neville Longbottom, I (with some help from Hakon) starting thinking about which roles in the Harry Potter series are being filled by players in this series. It's more about their role, than their appearance, now.
(This is obviously filled with spoilers.)
Andrew Flintoff as Harry Potter
The key figure in the fight for good - the hero of the saga.
James Anderson as Ron Weasley
The right-hand-man in the quest - in the past has been a bit useless, but now does well. Gets the hot girl.
Paul Collingwood as Hermione Granger
Really important to fighting against evil, but nobody particularly wants to acknowledge it. Works very hard, is good at the job she's given, but it doesn't feel right if she's in charge. (No Stuart Broad jokes)
Graham Onions as Neville Longbottom
He looks like him. And is also not particularly threating in appearance, but is able to chop off the top part of your order/snake
Stuart Broad as Ginny Weasley
Looks pretty, the important people seem to love them, but what do they actually do?
Michael Vaughan as Albus Dumbledore
The former leader, who has had great success in the past - but is no longer around. Has had other achievements, but will be most remembered for battling against the dark forces
Kevin Pietersen as Severus Snape
He's good, no wait he's
South Africanevil, no good, no South Africanevil. Used to be in charge, but had to hand the reins over.
Andrew Strauss as Minerva McGonagall
Now in charge of the good side, but everyone really preferred the other bloke.
Steve Harmison as Hagrid
He's a big bloke, isn't he!
Ravi Bopara as Terry Boot
Ian Bell as Dennis Creevey
Are you sure you're old enough to be here, mate?
Ricky Ponting as Lord Voldemort
The Dark Lord, the leader of all evil in the world.
Shane Watson as Bellatrix Lestrange
Fights for the forces of evil, yet is strangely, and unexplainably, ridiculously attractive
Mitchell Johnson as Draco Malfoy
Was given a job to do. Couldn't do it. However, the Dark Lord doesn't want to replace him, so someone else has to do the job for him
Troy Cooley as Peter Pettigrew
Used to be on the good side, but betrayed his friends to join the Dark Lord
Ben Hilfenhaus as Fenrir Greyback
Needs a shave
