Trivia / Doctor Who 2007 CS "Voyage of the Damned"
Bad Export for You / No Export for You: In Canada, the CBC - which in 2007 was the official broadcaster of Doctor Who in that country - chose not to air the special, skipping from Series 3 to Series 4 and leaving the cliffhanger at the end of Series 3 unresolved. Although it aired on a French-language branch of the CBC, it didn't get an official English-language broadcast until Space, a cable network, took over the broadcast rights to the series and finally gave the special a proper broadcast - a half-decade after it first aired in the UK. In the meantime, Canadian fans had to rely on either DVD releases or illegal downloads to see it.
Keep Circulating the Tapes: Technically the case for Canadian fans due to the episode not airing in that country for years; the only way for them to see the original English-language version in the pre-streaming era was to either buy the expensive DVD season set or download it illegally.
David Jason was approached to play the role of Mr. Copper. Sadly he proved unavailable. He'd probably have been more polite to the poor journalist interviewing the cast than Clive Swift was...
Dennis Hopper was offered the role of Max Capricorn, but wasn't available.
Word of God: Russell T. Davies wrestled with how to make it clear that the rest of the Titanic's crew and passengers weren't just a bunch of humans. It was only after it was too late that he realised he should have made them talk about "the humans" (in the third person) more often.
