I'll go with surpised for now. Though in some cases I was moved as well.
From a marathon I would say Frequency. Along the same lines, Equilibrium.
Non-marathon movie would be Searching for Bobby Fischer. The wife suggested it, I thought it was going to be more of a documentary looking for Bobby Fischer. A few years later my wife told me Lucas should have gotten Steven Zaillian to direct the young nakin scenes. If you have kids and haven't seen it, I highly recommend it. Runner up, only because I knew more about it, but still found it very touching in spots was October Sky.
I'm almost embarassed to put this here, but back in 1990, I had a brutal schedule in college and had taken a break from TV so I hadn't seen any ads for this movie. My friend Ken talked me in to going to see it, and based on the title I was expected a horror film. Yes, it is campy and silly, but it was so unexpected, I hadn't seen one ad for it, that I was suprised by
.
For suprisingly moved, I'll put in two Pixar films.
Up. I still am touched by the opening sequence, and find the room oddly dusty as I think about it as I am writing now. Same goes with the ending, with Russell's dad still absent and Carl filling in. I've seen too many cases like Russell's, so while the rest of the movie is difficult to suspend disbelief, those bits are all too real.
Wall-E. Yes, it is preachy at times, but the silent portions of the film have some of the same sweetness you find in a lot of Chaplin films. Especially his inteactions with Eve.
And someone Pixar picked up who has done good work, put out a very touching film in the Iron Giant. My older son was inconsolable the first time he saw it when the nuke went off with the Iron Giant.
