A movie made in 1999 combining comedy and horror and starring Bill Pullman, Bridget Fonda, Brendan Gleesan, and Oliver Platt with a plot revolving around a giant crocodile owned by Betty White.It spawned two Made for TV sequels with a third (titled, Lake Placid: The Final Chapter) on its way.
Brilliant, but Lazy - Kelly initially insults and rants at most anybody and anything around her and refuses to really help out despite having notable intelligence. That changes midway through when a charging bear gets eaten and she actually sees the giant crocodile.
Brother-Sister Incest: In a throw-away line: "The longer you live, the more sex you get to have with your sisters!"
To put it in context, Hank nearly falls victim to one of Hector's croc traps. When Hank berates him, Hector insists that it will end up saving his life. Because they dislike each other so much, Hector is presumably insinuating that Hank is an inbred, hick-town sheriff.
Conflicting Loyalty - Kelly struggles to try and mesh her feelings for Jack with merely trapping, not killing, the crocodile.
Conspicuous CG: Possibly invoked in the original, played straight in the sequels.
Curse of The Ancients - Mrs. Delores Bickerman, played by Betty White, jumps on this and averts it.
Deadpan Snarker - Everyone. Sheriff Hank gets a special mention, though.
Hank: (after Kelly freaks out about staying in a tent) Oh my God, we forgot the feminine napkins!
Death by Mocking - That's what they get for thinking Mrs. Delores Bickerman was crazy.
Deep South - Although set in Maine, Kelly immediately says that being in the woods anywhere is akin to being in the movie Deliverance.
Showing their research? I'm from rural Maine and people don't seem to realize socially it's a lot more similar to the rural South in many ways than it is to say Boston.
Hot Scientist - Kelly and on the male side, arguably Jack.
Huge Guy, Tiny Girl - Whenever Kelly is opposite Jack especially but also with Hector Cyr.
Humans Are Bastards - Mrs. Deloris Brickman for feeding cows to her giant crocodile. Hilariously, she later tries to pin this trope on the protagonists, insisting that they're cruel to want to capture/kill the man-eating crocodile in the lake.
Jump Scare - Used a couple of times with decent results, but the best one is the SECOND crocodile.
Tranquil Fury - Hank, after getting caught in Hector's trap. Hector even lampshades it:
Hector: I would let him down, but he has this odd look of mayhem on his upside-down face.
Truth in Television - As of September 4, 2011. A 21 ft crocodile was captured alive in the Philippines and there's reportedly more of them still loose. The Philippines just became a very scary place.
Vitriolic Best Buds - Hector and Hank seem to have become this by the end of the movie.
Volleying Insults - Occurs between Jack and Kelly, as well as Hector and Hank.
