I would say you are welcome but when he replied to my email today he couldn't remember, at first, and then he gave me the name of a movie rather than a documentary. Lol. He's had a pint or 500 since February.
I'm let down because he specifically told me it was a documentary. Anyway, he's now saying it's Taking Shelter, which I have seen the previews for and do want to watch. I keep hoping he's confused and will remember something else. Knowing him, anything is possible.
