Very true. Just look at the prosthetic hair Sean Connery wears in most of his current movies. From the point of view of the camera, it's almost impossible to detect the makeup work along the hairline of the prosthesis. I used to model as a kid, and from the front the clothes looked perfect. From the back, you wouldn't believe how many clothes pins were attched to me, pulling the clothes tight and eliminating any wrinkles from showing on the front, LOL.
