3-D Intent?

To begin - I KNOW that this film was not marketed or released in 3-D.

HOWEVER after watching it in simulated 3-D on my 3D HD TV [some models have an option that do that], I discovered that this film was framed and filmed ideally as though it might have been intended for 3-D photography at some point.

While there are thankfully no obvious 3-D gags, virtually every shot is composed and filmed with such depth of field that I get the impression that there may have been at least some thought right up until principle photography began to film it in 3-D. The scenes at the end, particularly, where characters are hidden amid bushes and obscured by shadow; as well as the scene where Gregory Peck is crawling through the grass, appears as though it were meant to take advantage of depth and movement between planes to convey its intent.

Are there any film scholars out there who can shed some light on whether this may have been a possibility?
