This clip has been spread round these here blogs like athlete's foot in a high school locker room, but don't think that'll stop me from posting it. Let it never be said that CRwM didn't go for the low-hanging fruit!
In the summer of '78, a group of 12-year-olds made their own version of the '75 Spielberg blockbuster Jaws. Here it is, in all its 8mm glory . . .
Interestingly, the original Youtube poster claimed that the reason the shark appeared in full only once was that it fell apart after the first scene. I find it a charming coincidence that both Jaws and Shark suffered mechanical problems with their toothy stars.
