Eric Roberts. WHY hire him? WHY WHY? He wasn't wearing the correct uniform and needed a haircut BADLY for being in the "navy".
The submarine existed of about $100 worth of materials. It looked like those zero turn mower handles were on it. The hatch was thinner than an aluminum garbage can lid. They did put 4 over size pressure gauges in the sub to make it look technical haha. This movie is NOT to be taken seriously. When the sub comes out of the ocean you can see another object underneath it lifting it up above water. There were no "monsters" in this movie at all. Just very poor cgi 3 second glimpes of a limb or something.
I've seen better High School movie productions from up and coming film makers. Yes, is is that bad. Only watch if you want to shake your head from side to side at the utter amazement that someone even financed this movie.
If I was in it, I would not put this on my resume. I'd swear I must have had someone look like me and steal my name. Yes, once a gain. It is that bad.
Evidently, so far the ratings of 1 seem to actually be telling the truth. One very positive reviewer must be one of the stars relatives.
