She Dances Alone (1981)

Director Robert Dornhelm casts Bud Cort for alter-ego purposes in She Dances Alone. Cort plays a documentary director, seeking to produce a film on the life of controversial ballet star Vaslav Nijinsky. He finds his goal of objectivity blocked by Nijinsky's elderly real-life daughter Kyra, who is as stocky as her father was sylph-like. Kyra's uncompromising insistence on total control over the project literally shapes (and frequently distorts) the film before our eyes. Adding to the Pirandellian atmosphere of the Australian-produced She Dances Alone is Max Von Sydow, also playing "himself."

Unfortunately the movie She Dances Alone is not yet available on HBO Max.
