Killer Crocodile (I don't think it has ever been released in the U.S.)
Italians are great people when we talk about making movies. Great people with loads of filmaking wisdom.
They know that making a bad movie is just pointless. If your movie is not gonna be good, at least make it unforgettable. If you are gonna be bad, be the worst ever.
They know that hidding bad FX is just pointless, everyone will notice them. Just show them as if they where awesome, in daylight, full frame and in as many shots as you can.
They know that hidding that their movie is a rip-off of another succesfully Hollywood movie is pointless, everyone will notice it. If you copy, then copy 'til the end. It's fine to copy full sequences and even the score. You just won't be able to release it in U.S theatres but, did you ever had any honest hope about that?
They know that if the script lacks in gore or nude scenes they have a problem. A problem easily fixed. It's fine to point a propeller mincing meat in full frame for more than 30 seconds and it's also fine to make some pointless women undreassing for no reason.
They know that hidding the creature doesn't create suspense. That's just an urban legend. People could miss the monster as it's easy to empathize him than the human characters. Showing him killing 3 or 4 people in the first 5 minutes is fine. Some could say that makes the rest of the attacks less shocking, but let's be honest, that shock never existed.
They know that the most irritating a character is, the better. That makes their death more satisfying.
They know that the only purpose of those characters is to be killed by the monster. So making them try to be eaten is fine. Also you could make them fail in their efforts some times, that really creates suspense. A sense of "oh, no, he is still alive!".
An Italian filmaker knows this and even more. And they show us all their wisdom in movie form, to make it easy to learn.
God Bless Italian Filmakers!
