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.
