Factual error: At the diner scene at the Gimli Slider, there's an ashtray with a lit cigarette on the table. Manitoba has had a smoking ban in all enclosed public spaces for over a decade.
Factual error: In the background, outside the Gimli Slider diner, you can see mountains. Gimli, MB is flat, and on the shores of Lake Winnipeg.
Continuity mistake: When Ali brings a fish to Wallace at the Manitoba Exotic Animals Park, she picks up the fish with her fingers pointing down at the fish. After a quick cut, she has a fifteenth grip on the fish. (01:33:05)
