Tammy Blanchard, who plays sexy secretary Hedy LaRue in the hit Broadway revival of How to Succeed in Business Without Really Trying, is headed for the small screen in Of Two Minds, a new Lifetime original movie produced by and co-starring Sex and the City beauty Kristin Davis. The film chronicles the relationship between a woman (Davis) and her younger sister (Blanchard), who has schizophrenia. The drama premieres on Lifetime on March 10, but you can get an early look at Blanchard and Davis’ heartbreaking performances in the video clip below. We're not surprised that Blanchard can do drama: She's an Emmy winner, after all, for playing Judy Garland in Me and My Shadows! Catch this talented star on TV, then get tickets to see her in person at the Al Hirschfeld Theatre.
