I disagree the adult performers in the Harry Potter films are all good actors, they have to be as it is an ensemble piece and they have very little screen time to make their characters believable. If they used inexperienced actors it would be terrible.
Helen McCrory was originally cast as Bellatrix but dropped out due to pregnancy which is how Helena Bonham Carter got the part. Obviously playing Narcissa is not such a good part but she did it well.
