In California, Susan Murphy (Reese Witherspoon) is waiting to marry her vain TV weatherman fiance Derek (Paul Rudd), who has just announced the news of a job offer in another state. Before the wedding ceremony kicks off however, a huge asteroid crashes down on top of Susan. and although she appears unaffected at first, the mysterious energy given off by the rock causes her to grow to enormous size. With her head now peaking through the roof and the guests running for their lives, the military are quick on the scene, capturing Susan and taker her to a secret government facility ran by General W.R. Monger (Kiefer Sutherland), who has been hoarding a collection of strange monsters for decades.
There she meets fellow captives B.O.B. (Seth Rogen), a boneless blob of blue goo; Dr. Cockroach Ph.D. (Hugh Laurie), a genius half-man, half-insect; The Missing Link (Will Arnett), a hybrid of sea creature and ape, and Insectosaurus, a gargantuan mutated bug. Their futures look increasingly bleak, but when alien Gallaxhar (Rainn Wilson) arrives on Earth in search of the crashed meteorite, US President Hathaway (Stephen Colbert), gives Monger the go-ahead to put his freaky prisoners to the test and straight into battle with the intergalactic invader.
B-movie fans will spot the homages immediately, and there's enough of a modern twist to the rag-tag gang of 'monsters' to delight any children watching. The references are obvious: there's Attack of the 50 Foot Woman, The Blob, The Fly, Creature from the Black Lagoon and Mothra, but the characters are so lovingly crafted and terrifically voiced by a talented cast that they feel more love letter than straight rip-off. Although there are a few laugh-out-loud moments, Rob Letterman and Conrad Vernon's film, working from a script by no less than five writers, fails to be consistently funny, and the arrival of Gallaxhar is a one-note plot device designed to bring everybody together. But there are some exciting set-pieces, particularly whenever the weirdly adorable Insectosaurus is involved, and there is enough heart woven into its fabric to make Monsters vs. Aliens one of Dreamworks' most underappreciated animations.
