"Because Percy has always been a minor principal and his storyline doesn't generally affect the main three characters, they've taken the decision to leave Percy in the dressing room for this film," said Chris.

"They don't finish filming until next March, so anything could happen – but from what I'm gathering, and that I haven't seen a script or a shooting schedule, Percy won't be around for GOF," he added.

Chris' contract to the Potter phenomenon does include another film at some point in the future.

"With the length of the books, it's impossible to include all of the elements and characters within the length of the film, so editorial choices have to be made," said Vanessa Andreis, head of Harry Potter production publicity.

"Elements that the film makers feel aren't vital to moving the story forward are the ones that won't necessarily be included, but that doesn't mean to say that these much loved characters, like Percy, won't be seen again in future films," she added.

The people I've spoken to have said the script doesn't mention Percy, the shooting schedule or cast list doesn't mention Percy – so I think you have to draw from that, that Percy's not going to be around - which is a shame as the bits he has in the GOF are very, very funny and important to the sub-plot.

The whole Barty Crouch thing, the judging of the tri-wizard tournament and things like that - but I don't know how much of that they're going to keep in the film. At the end it comes back to Harry and the whole fight against good and evil.

But you never know, they could change their minds over Christmas. Mike Newell might have a bit of Christmas cheer and think to put Percy back in.

I was talking to the twins [Jamie and Oliver Phelps] about it at the weekend. We were having a chat about how to do the quickstep, which apparently isn't going too well for some of them!

It would be nice to do OOTP, simply because Percy is such an backside (sorry, our filter doesn't allow the word he really used!) in it.

He's disowned his family and knowing my penchant for playing villains, it would be nice to come back and play the bad guy.

There's the scene with Percy at the beginning of the book where Harry is trialed for doing magic and the scene where Dumbledore is arrested about three quarters of the way through.

We then all joined them and stood for what was like a school photograph - in the cold and pouring rain!

Yes, it was nice to see everybody again, but as they're all working hard quite a few didn't stay too long.

I don't think Dan stayed for more than 10 minutes, but I know Emma was there until the end along with some of the older cast.

We got the DVD, I managed to get five of those! We also got a time-turner presented in what looks like a carriage clock case, there was Harry Potter Lego, packets of Bertie Botts' beans and jellied slugs - all sorts of bits and bobs.

The drinks were served like smoking potions in test tubes and there was a rather nasty looking pineapple drink in what, can only be described, as a specimen jar – people didn't drink many of them!

They also had these trays of canapés with broom sticks through the middle and serving platters created from giant spell books – it was a good night.

You can see me giggling in the background where one of the girls had accidentally stood on my feet.

I've been doing a drama with the BBC over the summer called The Writers' Club which will be out in the new year sometime. That was a complete change, set in the '70s - sex, drugs and rock 'n role – that's what it's about.

I've been working with my theatre company Painted Horse. We've just finished casting Salome which is performed in April/May next year and I'm back into panto over Christmas.
