US TV network versions aired censored versions of some episodes (removing, for example, rear nudity, paintings showing nude figures and some scenes of violence) with a TV-14 rating. These cut versions were released on Blu-ray in the UK, many of which received the more appropriate 18 rating from the BBFC. However, the American Blu-ray editions of the affected episodes are unrated and billed as Producer's Cuts, which restore the previously censored footage.
