You can`t pin marks on the wall-you`ll see it with the camera. Getting the actors to look in the right spot-you can`t tell them verbally you`ll step on their lines. ''When you`re doing split-scale, people don`t look at each other. ''Eye lines are critical they may have been our biggest concern from the start,'' Ellenshaw conceded. On the other hand, it`s difficult to choreograph the action to get the actors looking at the baby, and vice versa. In one way, this is very easy-there are no post-production optics to add to the shot. And you`re really going to fool a lot of people if you have two doors-a large-scale door and a split-scale door, and they look as if they open and close together, but in fact they`re miles away from one another.''

''There`s nothing wrong with building an L-shaped set, so that the baby can walk across the front, and the parents can walk across the back. ''The thing you want to avoid is having the split go down the middle, because that`s where everybody looks for it,'' he noted. Then, theoretically, everything lines up. You line up the smaller set and place it 43 percent closer to the camera than the larger set. ''The art department built these smaller sets. ''You build a duplicate set, in this case 43 percent smaller.''

Ellenshaw calls the process split-scale, or forced perspective.
