alan arkin
Just saw the film for the first time on my wife's recommendation. I don't know how I missed this being played on broadcast TV over the years. But I did enjoy it as a kind of time capsule of the early seventies.
I though Arkin's physical comedy was well done. He managed to invested the character with some sublety, despite the sometimes overbearing dialogue he had to deliver. The acting by all was good.
For some reason I enjoy the late-sixties/early-seventies portrayals of drug use. Often-times they seem like straight people's takes on it. I can well imagine the author flushing pot down the toilet twice paranoid about being caught.
