(20th C. Fox, 1970)
George C. Scott would be 86 today (he passed away in 1999).
This film earned 8 Academy Awards, including Best Picture, and Best Actor for Scott (which he declined, for foolishly transient reasons, IMHO).
He was a consummate actor, and this was truly a career pinnacle performance, and was an instant classic American movie. The anniversary of his birth is as good a reason as any to add this to the list here and now.
