Grew up with this movie. Really enjoyed watching it again.

Plot: Underwater deep-sea miners encounter a Soviet wreck and bring back a dangerous cargo to their base on the ocean floor with horrifying results. The crew of the mining base must fight to survive against a genetic mutation that hunts them down one by one.This is one creature film that has been largely forgotten by people and that's sad in my opinion. This film knew what it was from the beginning and that's what these films should be unlike Sharknado which makes these films look like one big joke. Everybody in the cast does a great job especially Peter Weller, Ernie Hudson, and Amanda Pays. Each character is likable and you really feel that these are real people. I personally feel the creature effects are very good even if it is somewhat like the thing they at least try to be something different. I don't get why the effects guys trash them, I just don't get it, but that's their opinion so I can't change that.This film is one of the better creature films from the 80s that deserves to at least have some respect from certain film fans. It has a great cast, good creature effects, a solid script, and very good direction by George P. Cosmatos. When you get the chance to watch this film, watch it you won't regret it.

I liked this movie even though it got a lot of ideas from the movies Alien and The Thing. This movie is about underwater miners mining silver; and discover that a lethal life form gets aboard their ship.When " Sixpack"(Daniel Stern) and "Elizabeth"( Amanda Pays) get caught pulling pranks on the ship; "Beck"(Peter Weller) assigns them to work duty the next day. The next day the two are venturing out on the ocean floor, ready for work. When Sixpack and Liz discover a Russian Ship(Leviathan) they explore it. Sixpack finds this box and they both take it back to see what's inside. The crew is stunned and find a videotape of the Captains Log. On the video the Russian Capt.(Eugene Lipnski) is explaining that his crew is dying off, due to some deadly virus. When Beck and his crew finish watching the tape they are stunned,they believe the Leviathan was deliberately sunk. They think the remaining crew sunk it to save the rest of the crew; and possibly to keep their virus secret. When Sixpack hides a flask of vodka in his pants he as well as the rest of the crew are doomed.Sixpack and Liz drink from the flask and the next day Sixpack realizes he has caught some type of virus. He goes to see "DOC"(Richard Crenna). The virus starts to get so out of control it ends up killing Sixpack in 8 hours. The crew panics and when Liz finds out what happened to Sixpack and how it transforms him she kills herself. The virus lives in it's host for awhile then it kills them, consumes their intelligence; and starts to form into some type of monster. It knocks a majority of the crew, and after each kill become more intelligent.When Beck contacts "Ms Martin"( Meg Foster) she gives him some crap story for not rescuing them right away. She explains that a hurricane is coming and their trip to the surface is delayed. so for the next two days the remaining crew will have to fight for their lives against this life form in order to survive. In the end 3 members to escape, but two only make it all the way back. The ending is priceless, and somewhat the AHHHHH moment of the movie.Even though this movie is not an original I still like it. The story a simple one about big corporations that value profit over human life. Those that have worked for big companies in the past know what I am talking about. This movie has some known names in it and some I never heard of, still good acting from all. So if you like Alien or The Thing you should like this movie. It is one of the better Sci-fi/horror films from the 80's so give it a watch.

I have now seen this film a few times, and have come to the conclusion that Leviathan is a shallow movie about the deep ocean. The premise is really the only interesting aspect of Leviathan, while the special effects, story line, and character development are lacking in quality. First, the SFX of this film are truly sub-par. Even though I understand the limits of practical effects, the effects in Leviathan are not convincing at all, and the designs are poor and lifeless. Compared to similar films, such as Alien (1979) and The Thing (1982), the special effects come off as cheap. This pulled me out of the film every time I saw the ridiculous lumbering mountain of wet rubber that was the ultimate monster. Second, the story line is basically a rehashing of Alien, expect taking place on Earth. It borrows heavily from The Thing as well, which all three have the archetypal scifi-horror story of finding a horrible creature trapped for eons, that is freed and subsequently wrecks havoc on the human characters. This in itself not a huge issue for me, but Leviathan added no interesting twist on this template, it just filled in the blanks. Third, the character development remained a low priority on the filmmakers mind. The characters are flat, and expendable. Peter Weller's character is the most developed, but still doesn't fill the necessary depth I need to care about him. In fact, the characters felt like a rip off of The Thing, even the Doc had a similar fate to Blair in The Thing. The spoiler part of this review is about the atrocious ending. It felt slapped on and shallow. The ending made this film go from just okay to bad.
