In the theater bathroom, where Ed finds Shari, (after pursuing her from the video store) they show a reaction shot of Shari's roommate watching at home. Then Ed goes out to the production van and, again, they cut to a reaction of Shari's roommate. She is wearing a completely different outfit.
When Ed is talking to Shari from the street, it's clearly raining pretty steadily. Everything outside is dripping wet and Ed's hair is soaked and rain noise is clear, yet his jacket is dry and no raindrops can be seen hitting the ground.
