One Hour Photo (2002)

The things that we fear the most have already happened to us...

Sy "the photo guy" Parrish has lovingly developed photos for the Yorkin family since their son was a baby. But as the Yorkins' lives become fuller, Sy's only seems lonelier, until he eventually believes he's part of their family. When "Uncle" Sy's picture-perfect fantasy collides with an ugly dose of reality, what happens next "has the spine-tingling elements of the best psychological thrillers!"
