Beautiful' is a must-see if you're a King fan, or you're fascinated by the music business during a potent time when chart hits were coming out of cubicles in places like the Brill Building and 1650 Broadway, where King and husband Gerry Goffin set up shop...With an understated performance, Mueller, seen recently in the Roundabout's 'Drood,' establishes herself among the elite of Broadway leading ladies. The actress, 30, doesn't sound much like King, but she makes each song her own while respecting the original imprint. She has lovely chemistry with Epstein, who you can't help but feel a bit sorry for: he's on his game, but Goffin, who is said to have suffered from manic depression, comes off mostly as a wounded misanthrope.
