John Barrowman revealed on Folge #11.10 (2006) that the line, "I'm really wired... What do you say I take you home and eat your pussy?" was intended to make Jenny McShane laugh, and was not intended to stay in the film. On Al Murray's Happy Hour (2007), he revealed that the actress, contrary to his expectations, gave no reaction. This was ideal as his line was dubbed to "...and watch I Love Lucy (1951)?" for the HBO TV version.
The German industrial band Synthetic Adrenaline Music (SAM) made a song called Bull Fucking Shit that incorporates audio samples from this movie including, "Bull fucking shit. You knew something was happening and you covered it up," and "They're gonna rip you a new asshole."

This movie got a lot of recognition after a clip from it showing the shark attacking a yacht went viral. That and a few other scenes have become popular Internet memes due to their bizarre dialogue and poor special effects.
On Shady & Shaky (2021), John Barrowman reluctantly revealed his being in Shark Attack 3: Megalodon (2002) and that it allowed him to buy his first place. This was revealed while he was sharing about being partly hired for the movie due to being a registered diver and that he was initially reluctant to go into a big water tank during the shooting because of the confusing contrary nods used by Bulgarians; when Barrowman asked a Bulgarian set worker if the cage in the tank was unlocked, the Bulgarian set worker nodded "no" while saying "yes".
