HBO’s forthcoming mini-series of David McCullough’s John Adams looks to be in the can, and you can now watch the teaser (with a rather breathless endorsement by the author) at the official site. (It begins airing March 16, presumably after the close of The Wire.) The cast includes Paul Giamatti (John Adams), Laura Linney (Abigail Adams), Danny Huston (Sam Adams), Sarah Polley (Nabby Adams), Rufus Sewell (Hamilton), Tom Wilkinson (Franklin), Stephen Dillane (Jefferson), David Morse (Washington), and Bad Putty Nose (Washington’s Nose).
