ACCM review

This review of the movie contains the following information:

A synopsis of the story

In this animated adventure, bride-to-be Susan Murphy (voice of Reece Witherspoon), is struck by a falling meteorite containing “quantonium”; a substance that transforms her into a giant before she can be married to her fiancé Derek (voice of Paul Rudd).  Captured and locked away for being a monster, Susan befriends other monsters detained in a secret government compound. Among them are B.O.B. (voice of Seth Rogen), The Missing Link (voice of Will Arnett and Dr. Cockroach (voice of Hugh Laurie).
Elsewhere in the universe, Galaxar (Rainn Wilson), a tyrannical alien leader on the trail of quantonium, discovers a deposit on Earth and wants it for himself.  Conflict ensues between aliens and earthlings so the government decides to send the monsters in to destroy the aliens and save the planet once and for all.  Now Susan has to choose whether to lead the rag-tag group of misfits into glory or return to her former life when given the chance.


Children and adolescents may react adversely at different ages to themes of crime, suicide, drug and alcohol dependence, death, serious illness, family breakdown, death or separation from a parent, animal distress or cruelty to animals, children as victims, natural disasters and racism. Occasionally reviews may also signal themes that some parents may simply wish to know about.

Destruction of earth; Separation from family; Aliens

Use of violenceinfo

Research shows that children are at risk of learning that violence is an acceptable means of conflict resolution when violence is glamourised, performed by an attractive hero, successful, has few real life consequences, is set in a comic context and / or is mostly perpetrated by male characters with female victims, or by one race against another.

Repeated exposure to violent content can reinforce the message that violence is an acceptable means of conflict resolution. Repeated exposure also increases the risks that children will become desensitised to the use of violence in real life or develop an exaggerated view about the prevalence and likelihood of violence in their own world.

There is some violence in this movie including:

  • Susan is roped, felled and tranquilised by the military shortly after becoming a giant. She manages to throw the offending tranquiliser dart at a soldier, piercing his foot
  • Susan beats one of the monsters, Dr Cockroach PhD, with her spoon
  • B.O.B., another monster, is thrown by Susan
  • The President says, “Do something violent”, so the military proceed to fire upon the alien robot probe
  • The President fires his pistol at the probe
  • A dart is fired from off camera at a Presidential Aide hitting him in the neck
  • Dr Cockroach PhD performs experiments on Susan whereby he electrocutes her
  • B.O.B. is repeatedly stood on by the alien probe
  • The probe pursues Susan through the city by smashing its way through buildings scattering cars and debris as it goes. A fight between Susan and the probe ensues on the Golden Arch Bridge.  There is much physical contact between them both and people in cars (as well as the other monsters) get caught up in the battle. The bridge is eventually destroyed and the probe’s head is severed
  • Insectosaurus (a monster) and Susan are attacked by another alien probe.  The audience is led to believe that Insectosaurus dies as a result
  • Susan is caught and trapped in a glass unit in which she has the quantonium extracted from her, causing her to shrink back to her previous size
  • Galaxar grabs Susan by her neck and throws her onto the floor
  • The Airforce One aeroplane is shot down by Galaxar’s ship
  • A cloned version of Galaxar detains Susan and forces her to the incinerator at gun point
  • The group of monsters come to the notice of the clones and a battle begins with gunfire and physical fighting
  • A clone trying to surface through a manhole cover is hit back down with it and squashed
  • An alien probe tries to destroy Susan by stomping on her
  • Susan flicks her ex-fiancé, Derek, into the air in anger and annoyance. He is caught and swallowed by B.O.B. who spits him back out
