LONDON - [WARNING: The last answer in this interview contains a pretty major spoiler. If you've seen "Prometheus, watch all the way through. If you haven't, stop watching when you get to the question about "Prometheus" sequels.]
 
When Ridley Scott spoiled the last scene of "Prometheus" in our video conversation in London last week, I knew I wouldn't be able to run the interview in the days leading up to the release of his not-quite-"Alien"-prequel.
 
That was a disappointment, because it was an enlightening conversation with the "Gladiator" and "Black Hawk Down" director.
 
Now, since "Prometheus" has completed a strong $50 million opening, I feel like enough people have seen the movie that the interview can go up, keeping in mind that my last question, discussing the way "Prometheus" largely functions as a set-up for a sequel, leads to Scott's spoiling the end of this movie.
 
[Repeated spoiler warnings are probably sufficient, right?]
 
In the interview, Scott addresses the obligatory "Prequel or not-a-prequel?" questions, but he also gives an interestingly pragmatic answer for how he came to be directing "Prometheus" -- Carl Erik Rinsch was originally attached, but the studio balked -- and the advantages he sees in returning to his sci-fi landmarks -- first "Alien," with "Blade Runner" next -- decades after they were born.
 
This is the last of the interviews I did at the London junket for "Prometheus." Check out my conversation with screenwriter Damon Lindelof and interviews with Logan Marshall-Green,  Charlize Theron & Guy Pearce and Noomi Rapace & Michael Fassbender.
 
"Prometheus" is now in theaters.
