THR has revealed that Kidman is making a cameo in "Anchorman 2" AKA "Anchorman: The Legend Continues." And that's it. No word yet on what her part might be, and like everything else regarding the movie, you'll just have to wait. But we'd wager it's a small, throwaway thing, and like Harrison Ford recently revealed about his appearance, it could very well be cut. So in short: we'll see.
The trade also says that Vince Vaughn (Wes Mantooth) and Luke Wilson will be making small appearances as well (the former already teased this a while ago). We guess one-armed Frank Vitchard is still going strong.
