This summer may be confusing to some less blog-literate moviegoers thanks to two recast roles. In both The Dark Knight and The Mummy: Tomb of the Dragon Emperor, a prominent character is played by a new actress. In the former sequel, "Rachel Dawes" will be played by Maggie Gyllenhaal, replacing Katie Holmes, who had the role in Batman Begins. In the latter, "Eveyln Carnahan O'Connell" will be played by Maria Bello, subbing for Rachel Weisz, who appeared in both The Mummy and The Mummy Returns.

This certainly isn't the first time characters have been recast with different actors, and over at The Onion, the A.V. Club has listed 20 such memorably jarring switcheroos, which they're calling The Darrin Effect (after the famous character replacement on TV's Bewitched), in television and film. Surely everyone recalls when Sarah Chalke took over the part of "Becky" on Roseanne; the writers even occasionally even slipped in some reflexive jokes about it. And let's not forget the glaring problem of recasting Jodie Foster's Oscar-winning role of "Clarice Starling" -- Julianne Moore played the part in Hannibal. Or the tragic yet surprisingly respectable replacement of Michael Gambon for a deceased Richard Harris in the Harry Potter movies.

Earlier this month a bunch of us came up with a list of the movie characters we'd love to have thanksgiving with. Now, here's the opposite. The title is pretty self-explanatory, so I don't need to set it up much. But as usual, we invite you to tell us of your own picks for worst Thanksgiving dinner guest. Please try to make it a movie character, though, because none of us know your annoying aunt, and plus this is a movie site.


Hannibal Lecter from Manhunter, The Silence of the Lambs, Hannibal, Red Dragon and Hannibal Rising

If you were to have Dr. Lecter (Brian Cox; Anthony Hopkins; Gaspard Ulliel) to your Thanksgiving feast, you'd want to prepare and cook all the food yourself. Otherwise, you might end up eating human flesh instead of turkey (or turducken, or whatever non-people-based meal you prefer). Then again, you might actually end up the meal, which is certainly much worse than unknowingly tasting Ray Liotta's brains. So, the best thing is to not even invite the guy.


Graham Young from Young Poisoner's Handbook

Another character who might be an interesting guest, but like with Lecter, you'll need to keep an eye on the food, or at least on the tea. Graham (Hugh O'Conor), aka "the teacup murderer" likes to play with poison, and there's a good chance he's going to spike the dinner or drinks with thallium.

Jimmy Carter may not have gotten a lot of respect when he was president -- maybe the fact that he was called "Jimmy" had something to do with it -- but he's enjoyed a resurgence in recent years as his humanitarian efforts have reminded Americans what they liked about him in the first place. He's not a great politician, but he's an honest, good-hearted man with noble intentions.

And now filmmaker Jonathan Demme (Talking Heads: Stop Making Sense, Neil Young: Heart of Gold) has scored with a documentary about him, called Man from Plains. Now playing at the Toronto International Film Festival, it was at the Venice fest, too, where it picked up three prizes last weekend.

The international critics' jury give the film its top award, while the Human Rights Film Network gave it a prize for best feature film. It also received the Collateral Award for Best Biography, which is presented by the Bologna Film Festival in conjunction with the Venice fest.

Sony Pictures Classics is releasing the film theatrically in October. It follows Carter on his recent tour for his book, Palestine: Peace Not Apartheid, which caused a stir with its controversial subject matter.

Demme is perhaps best known as a director of fictional films, including Philadelphia and The Silence of the Lambs (for which he won an Oscar). But his documentaries have been widely acclaimed, too. Many people consider his Talking Heads and Neil Young movies to be among the best concert films ever made. So his portrait of Jimmy Carter promises to be interesting -- and apparently the people in Venice think so, too.
