Lavender Brown has been cast!

One of the most anticipated roles in the Harry Potter movies has finally been cast! Lavender Brown, who is Ron Weasley's annoying love interest, is being played by Jessie Cave. Cave beat out over seven thousuand audtionees, and won the role. Although she is playing a sixteen year old girl, Cave is actually twenty years old. Below is a picture of the lucky girl. Hmmm... has anyone noticed that she is not black? It has been noted more than once in the first novel, and in the books following, that Lavender is African American. As puzzling as this is, I wonder if the director knew that he cast the wrong girl, or if he just decided to ignore the fact that Jessie Cave is as different from Lavender Brown as possible.
