The monsters shown in the movie are all references to original monsters in movies. Ginormica (Reese Witherspoon) is a reference to Attack of the 50 Foot Woman (1958), B.O.B. (Seth Rogen) is a reference to The Blob (1958), The Missing Link (Will Arnett) is a reference to Creature from the Black Lagoon (1954), and finally Dr. Cockroach, Ph.D (Hugh Laurie) is a reference to The Fly (1958).
The first computer animated movie to be directly produced in a stereoscopic 3-D format, instead of being converted into 3-D after completion.
For the scenes of Ginormica wandering the streets of San Francisco, a replica of the set was built, and Supervising Animator Line Korsgaard Andersen was videotaped walking around it as reference for the animators.
When the government agents arrive at the church to investigate the crash site, when the camera pans to the back of their van, when the door closes, you can see a camera crew visible in the reflection of the door.
The film has a localized version in Australia, where the News Reporter is not voiced by Ed Helms, but instead voiced by David Koch, a co-presenter of the morning show "Sunrise", seen on Channel 7 across Australia.
When Gallaxahr is talking to earth about what he is about to do, in the scene when Gallaxhar is talking in Times Square, New York City, on the top right corner, a scene from Madagascar (2005) can be seen of Marty talking to Alex.
The license plate of the yellow cars Susan uses as a roller skate reads "XQZMEEEE" or "excuse me", which she later says as she is skating through traffic on her way to the Golden Gate Bridge.
The famous sound effect, the "Wilhelm Scream", is featured in this film. The scream was originally done in the 1950s by Sheb Wooley, who sung Flying Purple People Eater (1958), which was used in the closing credits.
The two technicians who first discover the incoming meteor call the control center and issue a "Code Nimoy" alert, an homage to Leonard Nimoy.
While the President bears a slight resemblance to Stephen Colbert, the character's look had been finalized some time before Colbert had even been cast for the part.
When Gallaxhar says "UUUH! Fire phasoid cannon!" you can see the contrail left behind by the flying tennis rackets going past his eyes. The filmmakers also confirmed that.
The song, that the President plays on the synthesizer, is "Axel F" by Harold Faltermeyer, which was featured in Beverly Hills Cop (1984) and Beverly Hills Cop II (1987).
The large aircraft used to transport the monsters to San Francisco is based on an actual Guppy aircraft. The first Guppy was built in 1962 for NASA by Aero Spacelines of California to transport spacecraft components.
The President's code name is "Papa Bear" which is what Stephen Colbert calls Bill O'Reilly on The Colbert Report (2005).
General W.R. Monger's ('Kiefer Sutherland') insignia, on his right chest, is a combination of clouds and the title character of Shrek (2001)'s face, a nod to another DreamWorks "monster".
After Susan saves B.O.B., Link, and Dr. Cockroach from being crushed on Gallaxhar's ship, after becoming Ginormica again, Dr. Cockroach says "By Hawking's chair." This is a reference to Stephen Hawking, a renowned academic, who is bound to a motorized wheelchair, due to amyotrophic lateral sclerosis, also known as Lou Gehrig's disease, or A.L.S.
Early in the movie, B.O.B is bouncing a ball off the wall of his cell. This could be a reference to Hilts, the Cooler King (Steve McQueen) from The Great Escape (1963). McQueen played Steve Andrews in The Blob (1958) (B.O.B is a parody of the Blob).
The multi-colored pads that Dr. Cockroach dances on use the same sound effects as the light-up memorization game "Simon". The dancing in sync with the lighted pads is a reference to the arcade game Dance Dance Revolution (1998), in which you do the same thing, only in sync with the on-screen prompts.
The synthesizer that President Hathaway uses to communicate with the giant robot is a Yamaha DX7.
This movie is set in Modesto, California, the birthplace of George Lucas.
WILHELM SCREAM: During the fight with the "Gallaxhar" clones.
Insectosaurus is a combination of Godzilla, Mothra (of Godzilla's movies fame) and the Tyrannosaurus Rex from the Jurassic Park franchise.

Each Monster on the team is virtually immortal.
In one of the cities where Gallaxhar's message is being shown, there are blinking neon letters on one of the skyscrapers. These letters are Japanese katakana, and they spell "ka-ra-o-ke."

When the Monsters are fighting the alien spacecraft on the Golden Gate bridge, it shows a solid middle divider between north and south lanes. The bridge actually uses yellow removable pylons, so the amount of lanes on a given side can be adjusted for commute hours.

The large room, in which members of the U.S. Government meet up to use monsters as a form of defense against the aliens bears a striking resemblance to the war room from Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964). The character of General Monger even resembles and sounds like General Turgidson (George C. Scott) from that Kubrick film.
