I remember seeing a few Emmanuelle movies as a young man, but don't recall much about them. Although, they did cause me to permanently associate the name Emmanuelle with "super sexy raven-haired foreign beauty."
Initially, I thought that Adventures Into the Woods was originally shot as an X-rated film and then edited down to R, but I learned later on that it was intended to be soft-core from the very beginning.
I'd love to read the original books one of these days! Just need to find the time...
