 Due to being filmed out of sequence, the head shaving scene of  Scott Thomson (I) (qv) and Brant von Hoffman (qv) caused  problems when it was later determined that they would need to be  shown arriving at the academy beforehand, with their full heads of  hair intact. Producers worked their way around this by issuing wigs  for all of Scott and Brants scenes that play prior to the head  shaving.
