Transcript for 'Game of Thrones' tries to stop leaks of series finale
Just explaining "Game of thrones" to Michael here. We're back now with our big board and the incredible lengths "Game of thrones" is going to go to stop the leaks from their highly anticipated series finale. The purchases are said to be filming alternate endings of the series so no one, not even the mother of dragons herself or Amy robach knows who will end up on the iron throne until the finale airs and ABC's Nick watt joins us from Los Angeles with more. Good morning, Nick. Reporter: Good morning, Michael. Well, it's unclear how many endings they will shoot but the reason is clear. HBO has had a programming says it's so nobody really knows what happens. Nobody. So even kit Harington will have to sit and watch TV like the rest of us to see if he ends up on the iron throne. HBO fears leaks, hacks, slip, spoilers. In the summer a hacker leaked stolen episodes and also two "Thrones" episodes after slip-ups overseas and want to protect their finale for their own bottom line and I'd like to think also for the fans like Amy for their enjoyment. Right, I mean I wouldn't want to see anything leaked because I want to watch it as it happens and I really hope khaleesi ends up on the even throne. This isn't the first time a TV show has done it and no one knows which one is going to end up airing. No, it's happened before. "Breaking bad," "Walking did." "Sex and the city" and "Dallas," they shot sequences of every major character holding the gun so no one would know what to leak. When you had "Dallas," "Dallas cowboys" didn't have to worry about the internet. Looks like they're taking every super precaution and, Nick, do you watch the show? Are you agame of thrones" fan? I am not a massive "Game of thrones" fan but my guess for the ending would be that all the dead ones were just in the shower and they will come back. You know, there are other things you can do to kind of, you know, hide this. You know, you can make the ending really ambiguous like "The sopranos" and make it complicated like "The leftovers" or might be a big hoax and actually it's just designed to make us disbelief any spoilers that do actually leak. Before this airs in 2019, guys. 2019. I can't believe we have to wait that long. That far off? I will be anticipating it all the way. I did catch an episode. You brought me up to speed on it. I appreciate it. So good. Catch up.
