Reviews
Blackman has been reviewed by several print and web publications. The Times Jeremy Kingston said of her performance in The Wizard of Oz "Helena Blackman's voice soars to the yearning high notes, and yet she is not afraid to sing in the softest whisper. Every word is clear and cuts to the heart." Alfred Hickling of The Guardian also gave Blackman praise in the role saying "She gives a sparklingly assured performance, marred only by the usual drawback of appearing at least 20 years too old for a pinafore dress." The Stage said of her performance as Nellie Forbrush in South Pacific "...she exudes enthusiasm in the....numbers - especially the excellent Thanksgiving Follies scenes - and she looks perfectly 1940s." BBC Nottinghams Heather Hinchley also reviewed Blackman's performance positively saying "Without a doubt the star of the show was Helena Blackman".
