A Sci Fi Channel Original Movie released September 25, 2010, this film centers on the rampage of a half-shark half-octopus whose handlers have lost control of it.The film would later go on to inspire Piranhaconda, a sort of Spiritual Successor in 2012. Currently two sequels to Sharktopus are in development.
This film contains examples of:
All Part of the Show: Some of the beachgoers, including a pair of women and a father and son, wonder aloud if one of the titular character's attacks is all part of a show. One obnoxious teen lingers even after it starts eating people on-stage, snickering and saying "Awesome!".
Always a Bigger Fish: In the beginning of the film a beach girl is attacked by a shark while swimming off the shoreline, but the Sharktopus saves her by devouring it.
Artistic License - Biology: A surprising amount, even for a movie about a mix-and-match critter made up of two totally unrelated creatures.
Belligerent Sexual Tension: Andy and Nicole are less than cordial towards one another when they first meet, and for a while after that, but you can tell they're going to end up together by the end of the movie.
Roger Corman as the guy taking the old coin found on a beach. It also makes for a funny moment when he bites the coin to see if it's real. Given Corman's legendary...erm, frugality, you can just see him calculating just how many cheap b-movies he can fund with it.
Similarly, Corman's daughter, Mary Corman, appears as the bungee-jumping girl.
Imperial Stormtrooper Marksmanship Academy: For a guy with a submachine gun, shooting at a 20-some foot tall Shartopus (which tends to remain fairly still while he shoots,) Andy sure manages to miss a LOT of his shots.
Intrepid Reporter: Stacy actively seeks out the Sharktopus so she can cover the story. Her insistence to get up close and personal with the monster eventually gets both her and her cameraman killed.
Jerk with a Heart of Gold: Andy seems at first nothing more than a mercenary who loves cheap booze and cheap women, but he later refuses an offer of $1 million to not kill the titular monster. Mind you, this is just after his best buddy, Santos, is pulled overboard and chewed up, so Andy has a good excuse.
Immune to Bullets: The Sharktopus' main body can withstand machine gun fire. It's tentacles sort of float in and out of it depending on how they want the plot to unfold.
It's Been Done: Take a look at an earlier film with a suspiciously similar plot (minus the military angle) and a suspiciously similar monster: Devil Fish, an Italian Jaws ripoff made in the 80's. You know these people are scraping the bottom of the barrel when they rip off a godawful Italian ripoff. Thankfully, this film doesn't take itself as seriously.
Too Dumb to Live: Stacy has been pursuing the Sharktopus throughout the entire film just to get a scoop, has repeatedly witnessed just how dangerous it is, has already been rescued once before from being eaten alive by a timely intervention of the heroes, and yet still tries to document it when it already killed her cameraman and is approaching her at the end.
Turned Against Their Masters: After the device that enabled the scientists to control their project gets smashed, this happens—although it's not so much against its masters as it is against humanity in general.
Unusually Uninteresting Sight: An old man and a woman are on a beach with a metal detector. The woman finds an old coin, and is then grasped by the Sharktopus's tentacles, dragged into the water, and slain (all rather slowly). The man just stands there in Dull Surprise mode, waits until she is dead... and then goes to get the coin. Not out of place at all in a movie like this, though.
