ginger snaps (2000)

"Do you think I want to go back to being nobody?"
Ginger (Katharine Isabelle) is the older of two sisters who are considered the school freaks. Thus as outcasts they depend on each other for support. Then Ginger is bitten by a 'dog thing' on her 16th birthday and starts to change. She becomes preditory and wildly sexually active, much to her sister B's (Emily Perkins) annoyance, but blood is thicker and she ultimately helps her sister cover up her transformation.
Ginger Snaps melds the wolfman story to puberty, it becoming a metaphor for unsettling teenage change. Whilst this may sound a bit trite it actually works for the most part. Only when the film resorts to showing the transformed Ginger does the film dip.

the primitives (1962)

"We've got one week to enact the plan..."
A team of international jewel thieves are being tracked by a Scotland Yard detective, and soon starts to look closely at a nightclub act called the primitives. Could these seemingly innocent musicians and a dancer really be behind some of the most audacious crimes in recent years?
Looking every bit like a quota quickie, this interesting film is let down by some sizable leaps of faith, such as how the hell does a guy not recognise the woman he has spent the night with, even if she does wear a wig the next time they meet. There is also a distinct lack of thrills or tension, but is nevertheless intriguing enough to hold my attention for its 65 minutes.

an american werewolf in london (1981)

AKA The American Werewolf.
"The wolfs bloodline must be severed."
Two American students, David and Jack (David Naughton and Griffin Dunne) get stranded on the Yorkshire moors, whilst touring Europe. There they are attacked by a werewolf with Jack being killed. David is taken to and recovers in London, but is plagued by nightmares based on the attack and being a wolf hunting through London. He moves in with his nurse, Alex (Jenny Agutter) as she tries to help him overcome the trauma, but then Jack starts appearing demanding he kill himself, explaining that he has become a werewolf and all that David kills are cursed to walk the earth until he dies!
A supurb makeover of the werewolf story, This has it all, as long as you are looking for a wolfman with added gore and black comedy. This helped reinvent the horror genre at the time and still looks as fresh today as it did at the time.
