How many films have the actors signed up for?

[alhewison]

I have read various conflicting articles on how many films the 
children - and adult actors have signed up for.

Initially I had read that Dan Radcliffe etc had been signed for 2 
films - but have since read posts (in other news groups) that they 
have now signed up for PoA as well. I have also read that some of the 
adults (eg Richard Harris) have signed up for 7 films, but not Robbie 
Coltrane.

Has any of the above been confirmed by Warner Bros (I haven't found 
any confirmation)?

I also wondered why people are so sure that filming for PoA will not 
start until 2003 - why will there be a break now? 

I'm sorry if I've missed all the useful news links, but it's hard to 
distinguish between rumour and fact!

Thanks
