If you don’t like spoilers, then avoid any Doctor Who news or forums. An early release of the series 7 boxset includes the yet-to-air finale, “The Name of the Doctor.”
BBC Worldwide said in a statement:
A small number of US Doctor Who fans have received their series seven part two DVD three weeks early. We are asking fans who may have the discs not to divulge plot details so that fellow fans who have yet to see the episodes do not have their viewing pleasure ruined.
The Doctor Who official Twitter feed added:
Steven Moffat has promised if fans help keep the finale’s secrets, we’ll release a special video featuring Matt & David right after the ep!
