Casting directors working on the second Harry Potter movie have told CBBC Newsround Online that they aren't looking for any more extras for the film.
Hundreds of you deluged us with requests asking how you can appear in the next movie, which has now started shooting at Leavesden Studios, north of London.

We put your questions to Vanessa Davies, who runs publicity for the movie on location.
She said: "Our casting directors are really grateful for all the interest that so many children have shown.
"Unfortunately, we had to select the extras a long time before filming started, so all the positions are now full."

Child employment laws mean that every child has to get a "licence" to work, which takes several weeks to organise.
Also, arrangements have to be made for schooling on-set.
This means that no last-minute extras can be accepted.
How to become an extra
For the Harry Potter film, both specialist casting agencies and local schools were used to find extras.
According to Vanessa, the early starts (6-7am) and short working days made it sensible to use children who live nearby.

She added that there are no confirmed plans for the third movie, as they might decide to take a break or rethink what they're doing in some other way.
But she promised to update us in the New Year when there's more information.
Some pre-production filming took place on the second movie over the summer, but the "principal photography", which involves the main actors, only started at Leavesden on 19 November.
Shooting is expected to continue till summer 2002.
