Iron Man (2008)
When Tony Stark does this famous gesture in front of the explosion in Iron Man, you can first hear the sound of the explosion, and only later, do you see the flashes. But everyone knows that the speed of light (the explosion flash) is faster than the speed of sound. So it should actually be the other way around: first the light and then the sound.
As to Hagrid's parents, love will find a way, especially if one of them is a wizard.
BTW, I had a Korean friend who was incensed beyond measure that all the North Korean characters spoke with _South_ Korean accents in 'Die Another Day' — and even more by the villain's dad, who had a Cantonese accent.
