That's right. An absolutely, air tight, fully developed story will explore are four dimensions fully, but this is an exception rather than a rule in screenplays. Novels have the luxury of storytelling "real estate" in which to explore all of the character elements and their interactions in depth. Films are generally much more limited in the time (and "space") with which they have to spend illustrating the character element interactions. Therefore, exploring one dimension fully acts as a short-hand for exploring all four (much as Archetypal Characters act as a short hand for complex characters). You need only touch the other dimensions that differ from the "norm" that should be explored explicitly. I should note that more than one interaction can be done at a time, particularly if you have many objective characters present. Try to get as much mileage out of your storyweaving as possible by doubling or tripling up on your interactions, etc.
