The star of Yoko‘s film had many stand-ins. This was partly because the actor was incompetent, and mostly because it was an insect – a fly! There were actually a few hundred uncooperative little buggers on set. The naturally frantic flies had to be controlled for their performance, using sugar water.
Their co-star, Virginia Lust had an interesting part. She portrayed the set. The fly/flies walked along the landscape of her body – the curves, craters and ridges.
