10 Horror Movie “Mistakes” That Were Totally Intentional

10. Jones Disappears - Alien

At the end of Ridley Scott's Alien, Ripley (Sigourney Weaver) makes her escape from the soon-to-explode Nostromo, heading to the shuttle Narcissus while carrying the ship's cat, Jones, in a cat carrier.

But if you look closely during one shot, you'll see that there's very clearly no cat in the carrier - for a few seconds, light is shone through it and the carrier is obviously empty.

It's easy to assume this was simply a continuity gaffe, but there's actually a practical shooting reason for it.

Given that fire ends up shooting out of the hallway in front of Sigourney Weaver a few seconds later, Scott evidently didn't want to subject a cat to such a potentially traumatic experience, and so opted to shoot the shot without it.

Scott presumably assumed nobody would be paying that much attention to the carrier, but alas, in the era of Reddit and crystal clear freeze-frames, of course they did.

Once you know there's no cat in the carrier, though, you won't be able to un-see how roughly Weaver handles it, flinging the carrier around like, well, there's not a living thing in it.
