It's all change for the launch of Buffy's sixth season on BBC2.
Although the channel had planned to show Bargaining Part 1 on November 7th 2002, it now turns out that they are able to bring it forward one week to 6.45pm 31st October 2002 - Halloween.
Unlike the original US transmission, which was shown as a two hour special, part two will follow the week after, so there won't be a double bill.
