Continuity mistake: When Fin is talking to Nova and Lucas after the fog, the cut on Nova's cheek changes sides from left to right many times throughout the scene.
Trivia: In this movie Lou Ferrigno's name is Banner. In the 70s, Ferrigno starred in the TV show 'The Incredible Hulk' as the muscular green character who morphs from the character Dr. Banner when he's angered. Note that when the sharks are dropping in Secret Service agent Banner, who's protecting the VP, says, "Don't make me angry."Super Grover
Trivia: After the shark attacks the lifeguard in the pool it cuts to Nova's RV, and while Nova and Fin are watching Matt Lauer and Al Roker, notice the two Archie comics lying beside the laptop. Sharknado's director Anthony C. Ferrante collaborated with Archie Comics artist Dan Parent, and created a comic book titled "Archie vs Sharknado." It was released on the same day as this movie.Super Grover
