I remember seeing this as A kid,at the theater,and being scared.I look at it now,and laugh.Horrible film,Jaws Directed By Speilberg,accept no substitutes!
Yes, Jaws 3 was in 3-D. To this day, I have to watch the end of this movie when it's on tv, because the scene when the shark is about to break through the glass looks so terrible! The shark doesn't move, it just looks like a cutout moving towards the camera, but it was done that way for the 3-D effect. It's one of those things that I vividly remember from my childhood.
