I saw this as a kid and it scared me. I remember a sarchophacus was found and taken onto a cruise ship. At one point this girl on the deck at night see "red eyes" that tried to push her overboard. Weird things happen, and in the end they throw the coffin overboard where it lands next to a smaller child like coffin.... it was almost like the coffin needed to be near its baby or something.

Sounds perfectly creepy, I never heard of it but I'll have to look into it.

The whole thing can be watched on youtube
