In Forrest Gump, the scene where he goes to Jenny’s apartment and learns that little Forrest is his son, and asks in obvious fear, whether the boy is smart, or like himself. From there, all the way through Jenny’s funeral.
In Star Trek II, the scene after Spock’s death, where Kirk presides over a ceremony for launching Spock’s body away into space, when he says “Of my friend, I can only say this. Of all the souls I have encountered in my travels, his was the most human” with his voice breaking on “most” and then him having to gather himself to force out the word “human.” It’s just a brief moment, but very poignant, IMO, and probably the best moment of Shatner’s acting career.
Also agreed about Where The Red Fern Grows, Bambi, Old Yeller, and Steel Magnolias…
