"Christopher doesn't want anyone to ruin [the ending] and I completely understand that," Oldman told Contact Music. "The newer people on the film go to his office to read the script. They sent mine out, but it had to be hand delivered directly to me and nobody else. And the final few pages were missing. I went along and talked to Christopher and in person about the ending. Then I locked it away in my head."
To echo what the good folks at CinemaBlend wrote, you'll likely have to water torture Oldman to get the ending out of him. (Not that you'd want to ruin the entire movie for yourself, anyway.)
