Alan Rickman, who plays Severus Snape, is known to keep otters. This may seem like a good thing, but according to a source, he has been known to handle them brutally and even kill them. This might come from the fact that he has Irish ancestry or his close connection to Severus Snape. Also from the same source I heard that he is somehow related to both John Williams and Patrick Doyle. Could that mean something?
