I found this Roger Ebert review
, and was amused by the passage at the bottom. During an interview show Ebert was unable define the difference, but another guest was. He quoted a former head of the Toronto Film Festival about the movie Last Night
(the subject is an approaching apocalypse):
"Sandra Oh goes into a grocery story to find a bottle of wine for dinner," he said.
"The store has been looted, but she finds two bottles still on the shelf. She takes them down, evaluates them, chooses one, and puts the other one politely back on the shelf. That's how you know it's a Canadian film."
