After reading the handful of IMDb reviews, I believe the ongoing debate about how well Greaves executed his directorial vision is justified. I do like that I still wonder how much was planned and how much was impromptu. However, I'm not convinced the film makes a point.
What was so much fun for me is Patricia Gilbert's performance. In the beginning of her "screen test", I found her mesmerizing. She's angry, she's loud, she's enraged. Ironically, in a different "screen test", she downplays it, even lamenting when not filming that she thought she'd over-acted prior.
I was surprised by Susan Anspach's appearance. I recognized her from Five Easy Pieces with Nicholson, as well as other projects. It was a welcomed delight.
Although I will be watching this again when given the opportunity, I won't seek it out. I also don't recommend it for those looking for your typical, Hollywood send-up. It's for cinema addicts who enjoy experimental fare.
