Hired to play a fake witch on a TV remake of the Elizabeth Montgomery series, real witch Isabel (
Nicole Kidman) is thrilled, since she desperately wants what the original Samantha wanted, a "normal" (mortal) existence. Indeed, she promises her skeptical father (
Michael Caine) that she will no longer use her powers. Everything changes when she's cast as Samantha, costarring with Jack (
Will Ferrell), a fading movie star trying to resuscitate his career. Attempting to "steal the show," Jack hogs the spotlight, laughs, and good lines, pushing docile Isabel aside. When she's had enough, Isabel conspires with her flustery Aunt Clara (Carole Shelley), cynical assistant Nina (
Heather Burns), and squealy neighbor Maria (Kristin Chenoweth) to put a hex on Jack, so he will be nice. More than nice: he will be wholly devoted to his new paramour Isabel.
