Sorry for so many entries in rapid succession. One last thing for tonight:
Another of the previews I saw before Return of the King (which, btw, I quite liked, but more on that another time) was for The Chronicles of Riddick. As someone noted the other night, the preview wavered on the edge between "could be excellent" and "could be terrible." But then I figured out who the movie is about and what it's connected to, and now I'm pretty firmly in the "could be excellent" camp.
Specifically, Chronicles is a sequel to the 2000 horror/sf movie Pitch Black (see my review from a couple years ago), and although he never appears in closeup in the preview, Chronicles stars Vin Diesel. (If you know he's in it, it's pretty obvious that a certain shadowy figure in the preview is him.) Also, Judi Dench and Thandie Newton are in it, though I have no idea how big their parts are.
Chronicles is directed by David Twohy, who directed Pitch Black. It's also written by him, which may or may not be a good thing; he co-wrote the very solid Pitch Black screenplay and the excellent screenplay for The Fugitive, but he also co-wrote G.I. Jane and Waterworld.
So anyway, I'm tentatively looking forward to this one.
