Director Richard Rush clashed with producer/financier Andrew Vajna over the final cut of the film. Rush wanted his longer, eccentric, cut to be released, but Vajna wanted the shorter, and more conventional, 121 minute version released. Vajna eventually got his way.
In the scene when Dr Bill Capa (Bruce Willis) returns home from jogging, then opens his mailbox and a rattlesnake pops out, causing him to fall onto his back in fright, then he grabs a shovel from a gardener's truck and uses it to hit the mailbox causing the rattlesnake to jump out and slither off into a field, a similar scene happens later in the film. This is when Bill is being chased in his car by the menacing driver in the red car with the black windows. A gardener's truck gets crashed into on the freeway and some tools fall out of it. In both scenes Bill was in danger.
