I was about the same age as the protagonist when I saw the movie My Girl, and I left the theater sobbing.
Watched it again last night for the eleventy billionth time, and yup, still gets to me.
What was the first film you remember seeing that moved you to tears?
No idea - I’ve been watching movies since I was a child and am a notoriously soft touch emotionally. But the first movie I ever watched with my wife of twenty-nine years was The Elephant Man, and both of us were emotional wrecks by the end.

I lost it when the thugs started beating on Johnny 5 toward the end of film, when he screams “Noo, please stop. Noooo.” Seeing him acting in his usual friendly self even while being mutilated created a juxtaposition that overwhelmed my young brain.
