Corrected entry: When Mrs.Cummings and the dog's owner are being interviewed on TV, we see a studio hand fitting a Microphone to the owner, who is wearing a black top. When we cut back after they go back on air, the top is blue.
Corrected entry: When Gerry and Cookie check in to the hotel, and they have to sleep on a cot in the supply room, Cookie has curly hair pulled back from her face, it's clear from its perfection and shininess that there's already gel in it. Later on that same night, when they go to the mixer, she has her hair straightened and fairly elaborately styled. She couldn't have done that without having first washed her hair - it'd be a frizzy, sticky mess, no matter how much hair gel she used, if she tried to straighten it dry, with gel already in it. And it defies credibility that she'd have been able to fully shampoo her hair in the sink of a lobby bathroom.
