Hollywood tends to focus on short, intense scenes of pain stimulus such as beating, electrocution, etc. with a tearful confession coming after a few minutes.

The torture program had much more to do with long-term engineering of a prisoner's environment with the goal of breaking down his humanity and spirit over a period of months and years: stress positions, sleep deprivation, loud music, extreme temperatures, and repeated fruitless water-boarding.

I don't think we get to blame Hollywood for this. More like the techniques that our "advisors" were refining and teaching to repressive anti-communist regimes throughout the 20th century, finally applied by us instead of by proxy.
