The Scariest Moments In Non-Horror Movies!

[A-bomb]

Great list, Rog. Your first three picks were exactly the same ones that came to mind for me. Here are two others I'm reminded of:
1. Peter Jackson's Fellowship of the Ring has some scary parts, but the one that really got me was where Frodo shows Bilbo the ring and Bilbo's face turns monstrous for a split second.
2. In The Seventh Voyage of Sinbad, a magician places a woman and a snake into a big vase and turns them into a snake-woman thing. At first she seems happy about it and starts dancing around, but soon she seems to lose control of the snake tail, which wraps around her neck and starts choking her until the magician reverses the transformation. Not really terrifying now, but as a kid it got to me because of the horror on the woman's face when she starts getting strangled.
