* BackedByThePentagon
* DuelingMovies: With ''Film/{{Skyline}}''. There was a lawsuit over it and everything, primarily due to the same [[Creator/{{Hydraulx}} special effects guys]] doing work on ''Skyline'' while this movie was in post-production.
* FanNickname: The aliens are never really named -- there are lots of nicknames. Some call the aliens "[[FunWithAcronyms BLAAs]]" for "Battle Los Angeles Aliens".
* HeyItsThatGuy
** [[Film/{{Avatar}} Trudy]] somehow survived Pandora and traveled back in time just in time for the invasion and is now serving with the Air Force.
** Apparently, [[Film/TheDarkKnight Two-Face]] survived the fall, got a face-lift and some psychiatric help and enlisted in the Marines. (That or [[Film/TheCore Dr. Keyes]] saved the earth from below only to have to fight an enemy from above).
** [[Film/{{Transformers}} Leo Spitz totally forgot fighting transforming machines]] and starts to think about fighting aliens.
** Hey, [[Series/TrueBlood Hoyt]] is a Marine recovering from post-traumatic stress disorder!
** NEYO is in this???
** Looks like [[Film/RamonaAndBeezus Ramona is without Beezus]].
* TheMockbuster: The Asylum is at it again, with "''Battle OF Los Angeles''".
* Interestingly, the [[http://en.wikipedia.org/wiki/2011_T%C5%8Dhoku_earthquake_and_tsunami 2011 Tohoku earthquake and tsunami]] happened the day this was released in theaters, so as the movie about things coming out of the water and attacking Los Angeles was released, Los Angeles (and the rest of the Pacific Ocean) was under threat of a tsunami coming out of the water and "attacking".
