Trivia: After the underground success of the original film (considered a "so bad, it's good" cult classic), a sequel was eventually greenlit. Many feared the sequel would be self-aware and therefore not as unintentionally funny as the original. While it is true the cast and some of the crew were "in on the joke" and some inside-jokes were inserted for fans of the original, reportedly writer/director James Nguyen was trying his hardest to create a serious and legitimate sequel to the original film, which he considered an un-ironic "romantic thriller." Most of the self-referential inside-jokes in the film are the result of the producer and editor or the cast messing around... the script is actually almost completely earnest. (This is especially evident if one listens to the two audio commentaries for the film... Nguyen doesn't find the film nearly as amusing as the cast does).
Trivia: The infamous "Giant Jumbo Jellyfish" sequence isn't purposely bad as many assume. Nguyen was trying to show that the impacts of Global Warming (which is the explanation given for the birds attacking in both films) were beginning to effect other species, but because he blew much of his budget on more elaborate sequences (including renting out the famous "Jaws" backlot), the sequence was hastily assembled with no time and budget.
Trivia: In the opening scene, as Bill is being seated by Gloria, if you look closely you can see a copy of the script for the film in the background on a table. They were going over lines and someone set it down forgot to remove it from the shot before filming the take, but because it's slightly out of focus in the background and none of the words on it are visible, they didn't both going back to reshoot the scene. Just something funny to look for.
Trivia: Director James Nguyen was greatly inspired by the film "Sunset Boulevard", and thus includes several on-the-nose references to the film throughout. This includes a close-up shot of the sign for the actual "Sunset Boulevard" and including a key scene where a dead character falls face into a pool and is seen floating about, dead.
Trivia: The opening scene was supposed to be a reference to "Saturday Night Fever", but the production could not afford the proper soundtrack, and thus, Bill "strutting" down the street for a prolonged period now lacks any frame of reference.
