Nicole Kidman and Vince Vaughn to appear in 'Anchorman 2'
They'll make cameo appearances in the comedy sequel, which is due out this December
According to The Hollywood Reporter, Luke Wilson is also due to shoot a guest spot. Harrison Ford has already filmed an Anchorman 2 cameo and branded the experience "bizarre".
The newsroom sequel - officially titled Anchorman: The Legend Continues - started shooting last month (March) in Atlanta, Georgia. Original cast members Will Ferrell, David Koechner, Paul Rudd and Christina Applegate are all reprising their roles from the first film. Meanwhile, new additions to the cast include Kristen Wiig, James Marsden and John C Reilly.
Released in 2004, the original Anchorman was a parody of a 70s TV newsroom written by Ferrell and director Adam McKay. The pair have also teamed up to write the sequel, which is slated for release on December 20.
Speaking last year, director McKay revealed a few teasers about the sequel's plot, saying: "I don't want to give away too much, but I'll just give a couple of ideas that we've kicked around. Keep in mind we're still writing the story, but I'll say one phrase for you: custody battle. I'll give you that. I'll give you another one: bowling for dollars.
