Her bow in the 2002 Tony Award-winning Best Musical is at a special President's Day 2 PM matinee Feb. 16, followed by an evening performance.
Egan takes over the role from Sutton Foster, whose last performance in her Tony-winning part was Feb. 15.
Foster became a star for her ebullient, belt-voiced performance as the country hick who comes to Manhattan in the 1920s to be a modern woman. Foster's next project is playing Jo in Little Women, a Broadway musical version of the classic novel.
Delta Burke also exited Millie Feb. 15. Terry Burrell will play the Burke role of Mrs. Meers starting Feb. 16 until Dixie Carter steps in Feb. 23.
"I'm really excited!" Egan previously told Playbill On-Line. " I love [director] Michael Mayer! I love the show and I'm excited to get to do a happy 1920s musical. It's like the carbon copy of Cabaret — it's the polar opposite. The same time period basically, a little earlier. Same haircut, different story." Egan was Tony Award-nominated for her turn in Beauty and the Beast. Prior to the late 2003 Cabaret stand, her other credits include a prior stint as Sally Bowles in Cabaret as well as Triumph of Love, Putting It Together and State Fair. She also provided voices for the Disney film "Hercules"; the Japanese animated feature, "Spirited Away"; and the upcoming release of "Porco Rosso." The singer-actress will also release her third album, which will include a few Broadway tunes as well as music that she grew up with.
Millie has book and lyrics by Dick Scanlan (co librettist is the late Richard Morris) and music by Jeanine Tesori (her Caroline, or Change will come to Broadway in April). Ralph Burns and Doug Besterman won the Tony for Best Orchestrations, Rob Ashford won the Tony for Best Choreography, Martin Pakledinaz won the Tony for Best Costumes.
The only original principals still in Millie are Francis Jue (as Bun Foo), Anne L. Nathan (as Miss Flannery) and Angela Christian (as Miss Dorothy).
