Megan Mullally's hit series WILL + GRACE has finished its run, but she isn't leaving her character KAREN WALKER behind - she's planning to write a Broadway musical based on her. The star won an Emmy on Sunday (27AUG06) for her portrayal of the Martini-swilling secretary, her second Emmy Award for playing the part. Mullally says she hasn't given up on reviving the character that made her a star and wants to produce a Broadway show called KAREN: THE MUSICAL. She tells Entertainment Weekly, "I think it's hilarious. It's so, like, wrong. You're never supposed to keep (your old character) going. "But, see, that's what makes me want to keep doing it."
