I GOT A QUESTION...or two

Rating: 8/10 (20 June 2002)

Can anyone tell me what kind of whistle Madmame Hooch has (Glinnis Johns) is wearing around her neck. Why did they recast Snape. No offense to Kenneth Branaugh (a fine actor and I am still waiting for Hamlet on DVD. HOPEFULLY SOME TIME IN THIS DECADE) but I really really liked Alan Rickman in this part. Anyone know?
