Nods to Halloween and The Texas Chain Saw Massacre.

- The main girl being called Lori, a clear reference to Laurie Strode I thought.

- The opening skinny dipping scene "Mike? Is that you?". Reference to Michael Myers. Some people actually get Michael and Jason mixed up. Reminds me of that idiot interviewer who asked Jamie Lee Curtis about the Halloween films and mentioned 'the hockey mask'.

- When Will and Mark are getting their medication in Westin Hills, around the time the news report about Loris house comes on, The Texas Chain Saw Massacre (1974) is playing on the television. I'm ashamed to say how many viewings it took me to realize that's what was playing.
