A musical version of “Legally Blonde,” based on the hit movie starring Reese Witherspoon and the novel by Amanda Brown, will open on Broadway in April 2007.

The show, which has music and lyrics by Nell Benjamin and Laurence O’Keefe and a book by Heather Hach, tells the story of a determined young woman, who, when dumped by her boyfriend, goes to Harvard Law School in an attempt to win him back.
