Filming on Anchorman 2 is underway, but the flick continues to add great actors to its cast.  THR is reporting that Harrison Ford has signed on to play "a legendary newscaster a la Tom Brokaw."  Ford has settled comfortably into playing supporting roles lately, and he'll be sharing the screen this year in the upcoming films 42, Paranoia, and Ender's Game.  The size of his role in Anchorman 2 or how it will factor into the plot is unknown as details on the story remain scarce.  However, we know that James Marsden will play Ron's (Will Ferrell) nemesis, and that Ron is angling to go to New York City, which "is the holy grail for all newsmen," according to director and co-writer Adam McKay.  We can also look out for Kristen Wiig to play a love interest for the lovably legally-retarded Brick Tamland (Steve Carell).

The film also stars Paul Rudd, David Koechner, Christina Applegate, Meagan Good, Dylan Baker, and John C. Reilly.  Anchorman: The Legend Continues opens December 20th. [Update:  The first set photos have leaked online.  Hit the jump to check them out.]
