An international casting search was conducted online to find the actor to play Jay Moriarty. The scenes where actors are asked to prepare for their auditions are still viewable online through letitcast.com.
When Jay is out in the water searching for Frosty, he throws the bottle cap into the water and puts the bottle without the cap back on the board. When he peddles further the bottle cap is back on the bottle.
In the beginning when Kim throws the ball the first time for her dog to chase we see she is standing in Ice Plant, something that grows everywhere near beaches in Southern California, and where it grows nothing else makes it through. But when the camera shifts to show the dog retrieve the ball it's now showing just regular weeds like dandelions with no Ice Plant anywhere even though in the initial shot we saw that she was surrounded by it.
There is a sign on the door of Pleasure Pizza in the scene before Kim and Jay first kiss with a phone number that has 831 as the area code. The area code for Santa Cruz and Capitola was still 408 in 1994. The change to 831 happened in '98.
Frosty Hesson: We all come from the sea, but we are not all of the sea. Those of us who are, we children of the tides, must return to it again and again, until the day we don't come back leaving only that which was touched along the way.
