Alternate versions

The version shown on Australian cable television is the uncut version with a PG rating

The version that is seen on 7mate in Australia is completely uncut and PG. Some Blu-Rays rule the film PG. There is including something interesting that the GO! version when they still owned it to play on mainstream Australian television is rated M for "some violence"

To attain a more commercial PG rating instead of an M rating in Australia, the following changes were made:

• When the alien jumps from the building in the beginning, rather than hitting the ground with a "thud", he now sparkles away in midair;
• The scene describing what the bug does to Edgar's skin has been snipped;
• The fumigator's death has been shortened, removing the shot of the spray gun being rammed down his throat.
• The shot of the dead waiter stuffed under the counter is shortened

The UK PG-rated cinema version - as well as nearly all subsequent releases - have been cut by the BBFC to remove the two uses of the word "prick". The offending words were over-dubbed with the words "jerk" and "twerp". The uncut version was finally passed by the BBFC in 2017. It was rated 12 for "moderate bad language" and released on 4K UHD.

The Australian dual-coded DVD is the same as the censored UK DVD in the way that the two uses of "prick" are over-dubbed with "jerk" and "twerp".
