There's a plot of sorts, but it doesn't really matter. Fonda is like Candide, an innocent wandering through a world of wonders, though what we're really wondering is what creative way the filmmakers will come up with to have her remove her clothes, something that happens with gratifying frequency, starting with the opening credits, as the letters move about and try to cover her body parts.
Anita Pallenberg plays The Great Tyrant and Milo O'Shea plays the villain, Durand Durand (a group that didn't like the letter D got its name from this movie). John Phillip Law plays an angel. Marcel Marceau is in it, too, for those of you who love mimes.
Just watch the trailer in the previous post. Irresistible.
