One of my favourite film scenes ever was always near the climax of Aliens.  Slightly annoyingly screamy moppet Newt is being menaced by the Alien Queen when suddenly “whirr CLUNK” our heroine Ripley appears in her exosuit and, in the tone of a woman who has just discovered a wasp in her drink during a particularly nasty bout of PMT utters the line “Get away from her you BITCH.”

The sublimely talented Sigourney Weaver delivers those words perfectly.  Ripley has had enough frankly.  She has stuff to do. Let’s get the cute child away from the ugly monster and go and feed Jones the cat.  Look at her eyes though.  Ripley is determined but she’s also terrified.  Her only alternative is a one on one battle with something that arbitrarily picks off many of the film’s characters, including that really whiny bloke who seals his fate by repeatedly whining “game over man, game OVER”…
