9. The Stepfather
1987's The Stepfather often gets overlooked when thinking of some of the better offerings the slasher subgenre has served up over the years.
It may not quite be a top tier effort to rank alongside the all-time greats, but The Stepfather is a solid film that has an absolutely phenomenal opening sequence.
Starting off by introducing us to Henry Morrison - played by Terry O'Quinn of Lost fame - we find Henry in his bathroom, shaving off his beard, cutting his hair, changing his eye colour, showering, putting on a nice suit, picking up his briefcase and heading downstairs.
Sure, it's a tad odd to see such a dramatic transformation from scruffy mess to pristine businessman, but maybe Henry has had a rough day or two.
Instead of Henry having a bad time, we soon come to realise that it's his family who had really had it rough, as The Stepfather follows O'Quinn's character downstairs to reveal blood-splattered walls and his family all dead. Thinking nothing of this, Henry leaves the house, collects the mail, then whistles off into the distance to start a new life.
Joseph Ruben's '87 movie brutally sets its stall out in those opening minutes, with Henry soon becoming a real estate agent known as Jerry Blake, who has his own new family to terrorise.
