Both Otto Preminger and Dyan Cannon have admitted that the photo was fake. In fact, the model used was the girlfriend of Preminger’s son!

Roger Ebert interviewed Preminger in January of 1972, and wrote the following:

There have been reports that Dyan Cannon is furious with Otto because of a nude photograph in “Such Good Friends.” The photograph is of Dyan from the neck up and of an anonymous model from the neck down.

“Furious?” Otto says. “But she saw the photo on the set! What has she to be furious about? Doesn’t she approve of the model we employed? The model was a very good model, a wonderful girl. I should know. My son Eric is living with the lower half of Dyan Cannon’s body in the photo.”
