Well if you really don't want to see the fun, I'll give you a hint. It's not Event Horizon. And It's not House Of 1000 Corpses. And It's Jaws. Now you can figure it out on your own or just watch the hilarious little clip. I recomend the latter for you.
Now, personally I think it kind of ends in a fun little homage to Jason, the slow motion grab, I am sure that was not what they were going for. I mean they already did that. But I have been wrong in the past.
