They may have some bitterness that their stardom faded after it peaked with this film. I find it difficult to believe that they are feel in any way humiliated or embarrassed by the scene in question.

They’re just out for money, and that’s very disappointing - I always thought they were both dignified people, and the movie was beautiful.
