Is that the real official movie poster for Sicko?
It seems like there are 2 ways to read that poster and one of them is not good.
Is MM sitting in a US waiting room or is he in Cuba?
Probably the former, judging by the sign and newspaper, both in English. But the knock on socialized medicine and single-payer systems like British and Canadian health services is the long wait--unless Moore is predicting what will happen in the U.S. if they adopt his (mixed) message. Too, there is the possibility the poster was photoshopped.

Knowing the content of the film, I’d assume he’s showing a US waiting room, and folks having died, waiting for health care.
