All the main filming on Harry Potter and the Chamber of Secret finishes on Friday at Leavesden Studios, but a few more bits of info are starting to come out about this film and the next.

The best news is that Daniel Radcliffe, Rupert Grint and Emma Watson will all be back for the third film, The Prisoner of Azkaban.

That's the good news.

The bad news is, to give the children in the cast a good break, filming won't happen until at least early to mid-2003.

That means the film probably won't be out until 2004.

And it looks like an announcement about who will direct the Prisoner of Azkaban will happen in the next few days.

And there won't be for quite a few months, so the film company says there's no point in trying to contact them about auditions!

As soon as there's any more news on that, we promise to let you know.

He's played by British actor Robert Hardy. He's most famous for appearing in a long running BBC series All Creatures Great and Small.

And he played the doctor in Thunderpants!
