Thompson prepares for her Harry Potter role

Emma Thompson says she will be wearing “great, googly-eyed glases and Oxfam clothes” for her role in the new Harry Potter film, Harry Potter and the Prisoner of Azkaban.

The British actress will play Sybill Trelawny, the eccentric professor of divination at Hogwarts School of Witchcraft and Wizardry in the film, which is currently shooting at Leavesden Studios in Hertfordshire.
