As near as I can tell, this movie is based directly on Dr. Denton Cooley's career. Dr. Cooley WAS the first doctor to use an artificial heart in a patient whose heart was unrepairable on the operating table. He was chastised for doing this at the time without approval and so he started his own hospital, The Texas Heart Institute. This movie closely follows the circumstance of that operation that transpired in the 1960's long before the first APPROVED artificial heart was used in Barney Clark in December of 1982. I remember the time well as I had to wait an extra day for Dr. Cooley to operate on me as he was delayed in getting back to Houston after Mr. Clarks operation. This is one movie based on closely related facts.
