Factual error: The "US Lead Destroyer" attacked by the megladon is the Iowa class battleship USS Missouri (BB63). (00:29:00 - 00:31:20)
Mega Shark vs Giant Octopus (2009)
1 factual error
Directed by: Jack Perez
Starring: Jonathan Nation, Debbie Gibson, Deborah Gibson, Lorenzo Lamas, Vic Chao
Other mistake: In the scene with the plane that is attacked by the mega shark and subsequently crashes, the camera focuses on one character in particular- a man who states he is "getting married in a few days". It is assumed when the plane crashes that everyone on board dies, yet in the very next scene this man walks behind Deborah Gibson's character as an extra.
US Destroyer Captain: When we find the beast, we're sending him to hell.
