Snap decision

Blake's 7 proves that they don't make television like they used to - and that counts for behind the scenes as well. The final episode of the third series was meant to be the last, but when it screened, BBC director of television Bill Cotton, watching from home, enjoyed it so much that he rang up the TV presentation department and ordered them to make an announcement over the closing credits saying that the series would return next year. Just like that. Who says the BBC can't make swift decisions when it wants to?
