Deep Rising (1998)
The location may be posh - a brand new cruise ship on its maiden voyage - but throw in a group of up-to-no-good bandits, plus a deadly underwater creature, and this perfect example of a modern B-movie begins to take shape. Treat Williams is perfection as the reluctant hero, while Famke Janssen is deliciously foxy as an unsuccessful thief, and their in-the-heat-of-battle-romance is irresistible.
Director Stephen Sommers keeps a relentless pace going throughout the film, so you don't have time to think about how utterly ludicrous the whole idea is, and before you know it the film culminates in an awesome cliffhanger ending, which some people still don't get is a joke.
Even though the creature is created through computer animation, special makeup effect guru Rob Bottin was brought in to design the thing, a fantastically gross abomination, responsible for the film's most memorable moments
"Full scream ahead" the poster announces. That's true, but you'll be screaming with joy. So do that, and never forget to love it.
