Barbra Streisand and Walter Matthau create a compelling pairing within this amusing comedy drama centered on a marriage counselor ("Dolly") tasked with locating a suitable wife for the affluent "Horace." He possesses a somewhat grumpy disposition, presenting her with a challenge, but she presses onward, traveling to Yonkers where she inadvertently involves his two assistants, “Cornelius” (Michael Crawford) and “Barnaby” (Danny Lockin), in romantic complications alongside “Minnie” (E.J. Peaker) and "Irene" (Marianne McAndrew). The story concludes as anticipated, yet the unfolding events remain diverting to observe. The film largely showcases Streisand’s considerable talents; she delivers some sharp dialogue while wearing restrictive corsets and dancing in what appear to be uncomfortable lace-up boots. Gene Kelly's direction ensures the group dance sequences are exceptional—meticulously synchronized but retaining a sense of ease and vibrant energy. Jerry Herman’s lyrics shine through, with memorable songs like "Put on Your Sunday Clothes," "It Takes a Woman," and the Louis Armstrong collaboration that shares the film’s name, contributing to its brisk pace and overall enjoyment. Matthau's performance is remarkable; he wholeheartedly embraces the comedic tone, and Michael Crawford, despite not being my preferred vocalist, displays impressive agility that adds to the entertainment value. I was surprised at how rapidly the two-and-a-half hours passed, and those who appreciate high-quality musical theater will likely find this a delightful experience.
