There’s no place like home on a stage as a fantasy respite from a troubled life. Rupert Goold’s Judy (B) is the anticipated biopic with Renée Zellweger playing actress/ songstress Judy Garland in the fading fog of a salvage effort for money and maternal rights while in residency at a London concert hall. The story is slight, and the supporting characters make very little impression, but “Judy via Z” is a brass band of a performance. Ms. Zellweger finds the soaring voice (literally) and stirring humanity in a tragic real-life legend gone too soon. Through the haze of booze and pills, under puckered makeup and vice-grip hair and in poignant backlot flashbacks of being a controlled child performer in the Hollywood Studio System, there’s a stunning character portrait here. Goold conjures warm nostalgia amidst the melancholy and even captures some witty moments of acerbic humor. The music numbers don’t quite achieve the pulse of the moments in the margins, but you won’t want to miss a trip over the bittersweet rainbow with this talented woman of incomparable smarts, heart and courage.
