History Film / Sharknado3OhHellNo

* ActorAllusion: Lucas mentions to the guard at the military that situation could be worse if it was zombies instead of sharks. Said guard is played by Kellita Smith who also plays the main character Roberta Warren in Series/ZNation, a show about zombies.

** Kellita Smith as a military sergeant. Doubles as an ActorAllusion.

** The last two items are at least lampshaded:
--> [[spoiler:'''Gil''': How do sharks survive in space?]]
--> [[spoiler:'''Fin''': How do sharks survive tornadoes?]]

** Somehow [[spoiler:Gil manages to travel from the Hubble Telescope in low Earth orbit to the moon in a spacesuit with no propulsion.]]

** A rather obscure one that only German fans of the movies would notice, but the two people on the rollercoaster that April asks about her daughter are Oliver Kalkofe and Peter Rütten, the hosts of what is essentially the German version of MST3K.

* ProductPlacement: Scenes in the Universal Studios pre-shark storm are pretty much extended commercials.
** Pretty self-explanatory for the UsefelNotes/NASCAR scene, if you're familiar with how sponsorship works in the sport.

* UsefulNotes/{{NASCAR}}: A cameo from Brad Keselowski and Joey Logano. Footage is shown of sharks raining down on the track that is obviously just digitally altered footage from the 2014 Coke Zero 400 and 2015 Daytona 500. (However, the way that the sharks falling onto the track and cars is cleverly edited around footage of crashes and incidents from those races gives it a bit of NarmCharm.)
** As the race cars pull up into pit road during the red flag, [[spoiler:Brad and Joey get out of their cars to examine the hilarious situation. As Brad realizes it, he utters a TitleDrop and then gets eaten by a falling shark.]]
--->'''Brad Keselowski''': What's going on?
--->'''Joey Logano''': *points to the sharknado* That.
--->'''Brad''': *examines it, and sees an airborne shark falling towards him* ''LastWords'':Oh, hell no! *gets eaten*

Tropes:

*** Ironically averted in that [[spoiler: sharks actually ''are'' better-equipped to avoid ExplosiveDecompression than most other vertebrates, having no swim bladder or lungs to rupture. But hard vacuum still ought to boil their blood in their veins...]]

* TakeThat: Creator/GeorgeRRMartin's cameo and death was meant to mock fans who constantly bother him about finishing ''Literature/ASongOfIceAndFire'' before he dies. He also loses his head, something that is common in said series.

** A shark that lands on a roller coaster track slides along it on its own momentum instead of being torn apart or falling through.

** ''Series/StargateSG1'' star Christopher Judge (Tealc) as a secret Service agent.
