Which Oxford College is used as Hogwarts Hall in the Harry Potter films?

Answer 1

Harry Potter was not filmed IN the hall, but the hall in the film was based on the hall at Christ Church. As it is a working hall that college were not able to make the hall available to the production company for as long and to they extent they needed it. The scenes in the first film with the sorting hat were filmed on the stairs outside the hall. Some other scenes from the first film were filmed around the college. The college was used in the second film as a set, but only about half of the scenes filmed made the final cut, the others can be seen in the DVD extras. Much less location filming has been used from film three onwards, mostly owing to the financial success of the production requiring more elaborate studio sets.

Answer 2
