Warner Bros. have "done an AMC" and spoiled one of their own surprises in a piece of internally-developed blurb. I'll run it after this warning.
From the press notes for Wrath of the Titans (which, incidentally, I've seen and is pretty atrocious):
Neeson next appears in Peter Berg's actioner Battleship, and he also will be seen in Christopher Nolan's much-anticipated action thriller The Dark Knight Rises. Neeson is Liam, of course and not... erm... Is there another one? Who's up for a six part BBC series in which Liam Neeson travels around looking for public figures called Neeson, charting it all with a number of Powerpoint slides? I know I am.
Of course, I assumed that Neeson would be returning in The Dark Knight Rises, and in the role of Ra's al Ghul, since he more or less said so himself.
Thanks to Coming Soon for the press notes.
