Errors (FAIL) in the movies

It must be really complicated to make a film, and you have to have a top team to make it work. Reelz Channel presents us with mistakes in classic movies. It's still funny to see a guy in jeans, to see a cameraman in a scene or a kid who plugs his ears before the gun is even fired. Great work, and I really don't understand how people come to see errors that are so hard to find! Big UP.
