Yes, the German landlady / landlord who owned the house where a friend of mine lived was one of the few who survived that particular death march.
One of the more detailed sources on the tragedy is:
"The Brünner Todesmarsch Silent Memorials to the Genocide Against Germans"

Another source lists the general expulsion and mass murder of ethnic Germans in the East as one of the top ten genocides in history:
"Expulsion of Ethnic Germans after World War II (1945)"

EXCERPT "However, the forced displacement of some 14 million ethnic Germans and allied Slavs from Soviet Russia, from occupied areas of Eastern and Central Europe in the aftermath of World War II, has to go down as something pretty close to genocide, especially when one considers that between half a million and two million of them didn’t survive the journey.
While most of these deaths were from famine and disease, many German civilians were also executed outright, or sent to internment and labor camps by the Soviets" CONTINUED
I'm not holding my breath for Hollywood to come out with a Star-studded, Blockbuster movie about Allied war crimes and atrocities.
