The Grand Duchess and her husband met Helen Hayes, privately, in Toronto in 1958, not long before Colonel Kulikovsky passed away. I do not know what her reaction to the film was overall, but she did praise Ms. Hayes for her uncannily accurate portrayal of the Dowager Empress, as did many others who knew her,most especially Queen Elizabeth (the Queen Mother) who was herself, a mere few months older than Ms. Hayes.
Aside from the incredibly similar appearance and stature, the actress also naturally adopted Empress Marie's posture and demeanour with uncanny accuracy.
I know there are photos of that event, but I am not certain if the two of them appear together in any? If so, I shall post them.
Do consider also that although Grand Duchess Olga was not interviewed for background info for that film, other family members were, and thusly influenced the scriptwriters to make the story more of an epilogue (ie:, not reenacting the gory preamble) in deference to, the then numerous still living family members, which is how it did play out in the final production. And other than the fictitious "presentation" parties in the film, the "vetting" process of the apparent Anastasia was also quite accurate.
On an interesting aside, Hayes involvement in this film led to her great interest in Russian history, and later in life, Helen Hayes met & befriended Princess Vera Konstantinovna of Russia, who was living in retirement in near by Valley Farm, not far from her own home in Nyack, NY, just outside of New York City.
