I love movies like this. I love movies where the characters don't have names, they have titles. Here we have a two character film. One character is The Girl. The other is The Caller.The psychological head games they play on each other reach a bizarre level that makes for a truly fascinating viewing experience. A lot of folks, I suppose, will be turned off by the excessively talky nature of the script--the entire thing is nothing but dialog--but for those out there who are looking for something different--then The Caller is worth seeking out. Watch it if you enjoy Malcolm McDowall's acting.The whole thing keeps you guessing...very weird and well done.
