They Shoot Horses, Don't They? (1969)
Jane Fonda, Red Buttons, Susannah York, Michael Sarrazin, Bonny Bedelia & Bruce Dern
I'd heard this title most of my life and just assumed it was some "Black Beauty" type movie about horses.
Boy was I wrong!
This is one unique move that pulls no punches. I won't post spoilers, but will say that when you think of the various ways this story could play out and believe they won't go there when it comes the most negative of extremes... they go there.
It's almost hard to believe there was a time when the country was so desperate that people would risk their health & their lives (and in one case even their unborn child's life) to engage in a competition just for the promise of a little money (or that such deadly contests were ever allowed). But the depression-era "dance marathon" depicted in this movie descends into something reminiscent of ancient gladiatorial games where crowds would gather to watch the debauchery of contestants dropping dead from exertion or exhaustion (if not from actual combat).
At times, I got the same feelings from this movie as I got from watching
Rollerball (1975). This isn't a sports movie, but since it involves a physical competition with a last-couple-standing type of contest, it bears many similar aspects.
An eclectic cast with Gig Young stealing the show as the ethically-questionable Master of Ceremonies who will go to any lengths for the equivalent of ratings (which in this case translates into sponsor & spectator dollars as he continually ups the ante for the suffering contestants with various types of elimination derbies).
Al Lewis & Gig Young
As bleak & almost sickening as this movie is, I loved it because it hooked me & really caught me off guard with how it ended.
