Primal Rage

Mostly filmed around Crescent City, California, during the February each of two sequential years. That time frame and location were selected for the expected drizzle and overcast weather conditions. However, filming commenced near the start of a multi-year California drought and the production had to work around weeks of blue skies by using fog machines and hanging large drapes to block out the sun. It did finally rain a little the first year-- the last day of filming.

After the couple gets washed downstream they light a fire to warm up and dry off. One would assume that they had to scrounge for wood around them. However, the wood on their fire has very cleanly cut ends that were clearly sawed.
