Bruce David Klein’s latest documentary shows how a star was reborn into a stage and screen legend. Chronicling the complex period of Liza Minnelli’s life starting in the 1970s, just after the tragic death of her mother Judy Garland, Liza:  A Truly Terrific Absolutely True Story (B+), is star-studded and often dazzling. Viewers will get to see the documentary subject confront a range of personal and professional challenges on the way to becoming a bona fide icon. Over the formative years covered in the film, Liza seeks out extraordinary mentors in the fields of music and dance (John Kander, Fred Ebb and Bob Fosse among them) and fashion via Halston. With insightful participation from a coterie of colleagues ranging from Ben Vereen to the late Chita Rivera, along with revelatory participation by the star herself, it’s an intriguing look at the star’s rise and resilience. It is most interesting when she is most vulnerable. The episodic format with chapter titles and quotes is a little tedious, but ultimately it’s a definitive portrait of the lady.
