Visible crew/equipment: When Doug is pitching his idea to Christian, they are outside on the terrace of the hotel. As Christian is walking inside, he walks past some windows and you can see the camera and the crew in the reflection.
Continuity mistake: When Doug is dropping Andi off at her apartment, Doug is holding her purse open so she can get her keys out. When Andi gets her keys out, there appears to be a packet of tissues in the purse near the front. After Andi tries to grab the purse away from Doug, the packet of tissues is no longer there.
