I love it when I catch movie mistakes. It does kind of ruin the movie from that point on, but still cool to catch! Sometimes it is something missed that is real subtle. Like a button that is buttoned in one scene and unbuttoned in another. Or a drinking glass in one scene and gone in the next.

In this video I knew some of them like in Gladiator and Back To The Future III. I think the one that shocked me the most was mistake made in the original Jurassic Park. I won't spoil it here. You will have to watch it to find out.
