Because the show often ignores continuity if it would prevent funny and crazy stories, the producers took the unusual step after the Season 9 premiere of announcing that the events depicted were 100% part of the series canon--and that the deaths of characters such as Diane Simmons, Muriel Goldman, Derek Wilcox and James Woods would be part of the show's stories going forward. However, in Season 11 James Woods is magically returned to life, with the surreal explanation that he was revived via the life force of a teenage girl because that kind of re-animation is available to celebrities in the Family Guy universe.
