Some, er, questions...for those who've seen this

- What exactly is Mr Hunter advertising by sending two women into the middle of the ocean in secret? The boat?

Yes, the boat.

- Why, when it goes wrong, doesn't he call the authorities and say, I was running a secret ad campaign and it's gone wrong, can you help find the people involved? If he's such a huge sports magnate, surely he could keep it out of the press...

It's hard to keep things out from the press.

- Why does Noemi have to be kidnapped?

So she doesn't leak the story to the press.

- Why, when escaping, does Noemi go to the trouble of PUTTING ON her noisy high-heeled shoes???

I have no idea.

- Why, when Lorena's gone missing on the Galleon, isn't Cathy worried? She doesn't even call her name, just turns on the radio and falls asleep...doesn't she wonder what's happened?

Surely she doesn't expect the ship to be full of zombies.

- Why, when being killed, does Noemi keep calling the name of the man WHO RAPED HER? WTF?

Good point. I don't know why she decides to call HIS name and not one of the others, but he's on the boat. I don't think this was something they even thought about when they made the movie.

- Lillian and Mr Hunter decide to kill Noemi and the Professor if the need arises, because they'll just be unexplained disappearances...so why didn't the Professor tell anyone where he was going?

Well, they were leaving in a hurry.

- Why was an 18th-century Dutchman transporting some captured Knights Templar...in packing crates? Were they already dead? I mean, undead? If so how did he get them to behave?

They were already undead. I understod it as he wanted to be part of their cult and also become one of the undead.

- Just how bad is Noemi's acting?

I've seen worse.

"What does it do?"
"It doesn't do anything. That's the beauty of it."

A lot can be explained by the fact most people in de Ossorio's films are so mentally, physically, and morally inept, and have the survival instincts of lemmings, that it would be an insult to the vast majority of retarded people to call them retarded.
Tombs and Ghosts Galleon are the worst examples of this where it seemed the characters were literally begging for death. The films of de Ossorio's that I've seen (to be fair only 6 of them) also seem to have laughable levels of disrespect for women, with them being more physically and mentally inept than the men on average, not to mention the rapes and casual lesbianism (though both of the latter seemed strangely abundant in Euro flicks from the 60's-80's, so it wasn't really just his films).
I have a semi-mentally retarded (and I mean actually retarded) cousin and he is at least 10x smarter and more physically able than the people in Ghosts Galleon and Tombs of the Blind Dead. I mean the Blind Dead have the walking speed of a 90 year old woman with crippled arms using a walker, yet these people cannot seem to get away and seem to think standing still and screaming at them is a fantastic substitution for even walking at a leisurely pace away from them.
