Generation (1985)

Futuristic prospective series pilot, a distant cousin the 1975 theatrical violent sport movie "Rollerball," revolves around a turn-of-the-millennium family on the Great Eve (the night before the year 2000 begins) planning for a reunion. Son Richard Beymer is an inventor working with prosthetic devices to help young athlete brother Drake Hogestyn perfect his game of combat hockey to maintain his skills as a national hero, and Cristina Raines is a socially conscious doctor who wants nothing to do with their prideful father, Bert Remsen, to the distress of their loving mother, Priscilla Pointer.

Unfortunately the movie Generation is not yet available on HBO Max.
