I agree that "All These Women" is misunderstood, especially if you look at it in the context of Bergman's filmography. He had just completed the "Silence of God" trilogy, one of the deepest, most serious works in the history of cinema. So, cut the man some slack and allow him his lark, his goof, his chance to riff on fans and critics and the illusion of the exalted artist (himself), before returning to his true work with his next film, the universally praised "Persona."
I also think he was a little influenced by "8 1/2" which had come out the year before, appreciating Fellini's playfulness as well as his insight into the creative process and, of course, "all these women." Bergman will always be thought of as a somewhat austere and oft despairing artist, but thankfully we have several films that belie that, like "Smiles of a Summer Night," "The Magician," and this little oddball gem.
