Where were the Harry Potter films filmed?<|im_end|>
<|im_start|>assistant
The Harry Potter films were primarily filmed in the United Kingdom. The majority of the filming took place at Leavesden Film Studios in Hertfordshire, England. Other locations across the UK were also used, including the University of Oxford, Gloucester Cathedral, Alnwick Castle, and the Scottish Highlands. Some scenes were also filmed outside of the UK, such as in Switzerland and Norway.<|im_end|>

No, J.K. Rowling mandated a strict British-only rule for the films.  When "Harry Potter and the Sorcerer's Stone" began production, Director Chris Columbus made an agreement with author J.K.Rowling to cast exclusively British talent. This decision ultimately led to the rejection of actor Robin Williams who auditioned for a role in the film. In an interview, Casting director Janet Hirshenson stated that the "Only British" policy was strict enough that even Robin Williams was denied a role in the movie. Despite this, one exception was made for Chris Columbus's daughter Eleanor Columbus, who played the character of Susan Bones, but was forbidden to speak. She appears briefly at the beginning of the film during the Sorting Hat scene.<|im_end|>
