I'm not sure specifically which 'Paul Hammersmith' you are referring to. There could be many people with this name. Without more context, it's difficult to tell the real story.
Well, Wolf Creek is not based on actual events. It's a work of fiction that uses elements of horror and suspense to engage the audience. The story was crafted by the filmmakers' imagination rather than real-life incidents.
Wolf Creek 2 is purely fictional. The plot and characters are made up by the filmmakers to thrill and scare the audience. There's no real-life basis for it.
