TWO sequences of ABSOLUTE GENIUS in this movie
1. Watch the sex scene - Steven Dorff and Juliette Lewis. Notice the camera angle and where Dorff appears in it. Shortly after there is the shot of Dorff mowing the grass (we only know Dorff is mowing because of the sound effects) whilst the family are in the pool, and Dorff is in exactly the same position as in the sex scene, with the family in the background.
2. Steven Dorff approaching the family with the snake is sexual symbolism at it's most potent. Look at the way Dennis Quaid's character backs away in fear.
