When Samantha chases the dog, she goes between shots from her suburban neighborhood to a clearly urban alleyway.
Samantha's hair changes styles between shots when she's talking to the police.
When Samantha takes hot roast out of oven to check if it's done she uses oven mitts to pull out hot roast pan. But when she goes to push it back into oven to finish cooking, she just touches scorching pan with just her hands.
